Growth is a whole process which includes growthof the body as well as growth of various aspects ofchilds personality, e.g., the physical, emotional,social and cognitive development.Development is a progressive change the childundergoes which increases the physical, social,mental and emotional capacities of the child.

1.The effects of dietary docosahexaenoic acid (DHA) supply during infancy on later cognitive development of healthy term infants were evaluated in a randomized clinical trial of infant formula milk supplemented with 0.35% DHA or with 0.36% DHA and 0.72% arachidonic acid (AA), or control formula which provided no DHA or AA. Fifty-six 11-month-old children (26 male, 30 female) who were enrolled in the trial within the first 5 days of life and fed the assigned diet to 17 weeks of age were tested using the Bayley Scales of Infant Development, 2nd edition (BSID-II) (Bayley 1993) at the Retina Foundation of the Southwest, Dallas, TX. Supplementation of infant formula with DHA+AA was associated with a mean increase of 7 points on the Mental Development Index (MDI) of the BSID-II. Both the cognitive and motor subscales of the MDI showed a significant developmental age advantage for DHA- and DHA+AA- supplemented groups over the control group.
2.A prospective case-control study was to assess the effect of prenatal depression on newborn and 1-year-old infant characteristics as related to gender, controlling for confounding variables. As such 205 pregnant women were screened for major depression. Inclusion in the prenatal depression group (n = 34) was based on meeting DSM-IV criteria for major depressive episode. Newborn and 1-year-old infant character ristics were evaluated with the Neonatal Behavioral Assessment Scale (NBAS) and the Infant-Toddler Social and Emotional Assessment, respectively. Male newborns of mothers with prenatal depression had lower scores than controls on the motor skills and regulation of states NBAS clusters. At 1 year, infants of prenatally depressed mothers presented higher scores on generalized anxiety, particularly in male’s activity/impulsivity and sleep problems than controls
The period from 1 year to 3 years of age. The individual emerges from the total dependency of the infancy into beginning independency or autonomy. The toddler who learns to trust the parents during infancy now can use this trust in exploration and investigation of a world beyond parent’s arms.
1)Physical growth Rate of biologic growth slows downcompared to that of infancyWeight and height : . The average weight at 2yrs of age is 12 kg at 2 ½ yr child weighs 4 times that at birth.This slowing of weight gain leads to a reduced metabolic rate which results in a decreased appetite. The gain in height is greater than that of weight in toddler period. Height increases 10 to 12.5cm /yr due to growth in length of legs. The height at 2 yrs is about 85cm. Boys tend to be slightly taller than that of girls.
Body proportions The young toddler has a relatively large compared to the size of rest of the body. The head circumference during the second year increases by 2.5cm. By 2 years of age the chest circumference exceeds that of head. The rate of increase in head circumference then decreases so that by 5 yrs of age the increase in circumference is less than 1.25cm each year. The trunk is long in relation to the length of the legs. As the circumference of the chest increases the transverse diameter also increases and becomes greater than the anteroposterior diameter. The abdomen protrudes making the child appear pot-bellied because of the immature abdominal musculature. The legs may appear slightly bowed during the second year because of the weight of the rest of the body.
Dentition : At 2yrs toddler will have 16 teeth. At 2 ½ yrs the full set of 20 temporary teeth has erupted. Physiologic development: The physiologic function of body is mature except endocrine and reproductive system.
2)Motor Development Muscle grows faster than bone during the toddler period. The size of the muscle as well as their specificity of movement increases as a result of use. As a toddler, walks, runs and climbs the muscle used in these activities increase rapidly in strength.
3)Sensory Development Although the binocular vision is fully developed by the end of infancy depth perception does not appear completely until childhood. Visual acuity is 20/40 at two years of age and 20/30 at 2 ½ years of age. Increase visual acuity permits the learning of depth perception and colour discriminations The other senses hearing, taste, smell and touch continue to develop during the toddler period. The sensation of pain and touch are more fully developed than in the infant
4)Language & speech The development of receptive, expressive, and language skills proceeds rapidly during the toddler years. The vocabulary increases to about 200 words by age 2 years. By age 2 the child is typically able to use pronouns, state his or her own name, and ask simple what, where, or why questions.
5) Play Symbolic, imaginative play. In functional play the use of objects is constrained by the appearance or function. As cognitive and social skills increase the use of play materials becomes much less dependent on the actual characteristics of the play materials so that the cup can be used to stand for boats, bathtubs, and so forth. Play activities also serve as an important opportunity to develop peer relationships. The children play alone but together. By age 3 the child is typically interested in more cooperative play that involves mutual negotiation of rules, shared use of materials, and so forth.
6) Needs of the toddler Love and security Discipline leading to self control Progression to independence Achievement of control of bodily function
Cross-sectional research indicates a positive but inconsistent association between language and self-regulation skills throughout toddlerhood. They used growth modelling of longitudinal data for 120 toddlers collected when children were 14, 24, and 36 months to test the impact of two expressive language skills - spoken vocabulary and talkativeness - on the growth of toddlers self-regulation, and to determine whether associations between these domains exist when controlling for cognitive development. Results reveal that vocabulary is a better predictor of self-regulation than talkativeness, and both concurrent and prior vocabulary positively predicted childrens levels of self-regulation. When cognitive development was controlled, 24-month vocabulary still predicted the trajectory of self-regulation. Results reveal that, even in early development, words are tools that can be applied to the task of self-regulation, and may be a more necessary tool for boys than for girls at this age.
Preschoolers are children who are 2 to 5 years of age. This time period is a stage of continuing growth and development for young child. During these years, children change from clumsy toddlers into lively explorers of their world. He will go through many changes in his physical, mental, emotional and social development. School-age children range from 6 to 12 years of age. This time period is a stage of continuing growth and development for young child. During this period a child will experience a wide variety of physical and developmental changes, but not every child experiences development at the same rate. He will go through many changes in his physical, mental, and social development.
1.Physical or biologicPRESCHOLER SCHOOLAGE The growth of particular body parts may reachIn these years, a maturity during this time child becomes height may be about 43 and one-half inches. stronger and Weight may be about 43 pounds. Later, as puberty starts to look starts, your childs height and weight will increase longer and quickly. On the average, a childs height may reach 59 inches at age 12. Girls are likely to weigh more leaner. On the than boys average, Temporary teeth fall out and permanent ones preschoolers replace them, the mouth has not reached its full may gain an size and the adult teeth may begin to crowd average of 4.5 to Secondary sex characteristics begin to appear as 6.5 pounds every children enter puberty. the age at which these changes occur can vary from child to child year. Girls may begin to develop breasts and pubic hair, while boys will experience development of the testicles and penis, as well as the growth of chest, underarm and pubic hair.
2.Motor and self care PRESCHOLER SCHOOLAGE Motor (movement) skills improve Fine motor skills may also vary along with his balance and widely. can affect a childs ability to coordination write neatly, dress appropriately, and perform certain chores, such as Body control or movement: able making beds or doing dishes. to stand on one foot even for a short Good hand finger coordination period of time,walk up and down Feeding skills: Self feeding with the stairs alternating each foot to occasional spilling, distinguish skip and throw a ball, child learns between finger and spoon feed, to dress and feed himself, and use chews with mouth closed the toilet on his own. Dressing skills: Puts arm through Hand and finger control: can hold large armhole, unbuttons large front a book or pen more firmly,learns to buttons turn paper pages. Later, he is able Toileting and grooming skills: to turn paper pages one page at a Night time bladder control begins, time, and write his name. may go to toilet by self.
3.Language and Speechdevelopment Receptive language: Language becomes socialized *identifies 5 body parts when and communicative named. Language is used by the * identifies one or more parts of preschoolers to communicate body when named their feelings and ideas. Expressive language *gives full name if asked *uses appropriate pronoun when referring to self-I * uses plurals and past tense of verbs *talks constantly *ask why?
4.Play Parallel play: children enjoy being with each Parallel play continues, helps other, but they do not put things away, pretends in interact very much. They will play side by play side, watch, and listen to each other. They Motor play like pushes and sometimes may fight over the same toy. steers toys, large cars and Associative Play :Children still are doing trucks, interlocked blocked their own thing. They often do the same trains thing as other children, but they do not do it Creative play like clay, together. Children sitting side by side in a crayons, finger paints, sing sandbox will repeat what the others are songs, large wooden puzzles doing. Quiet play with cloth or Cooperative Play:When speaking and cardboard books, toys for listening skills are more developed, children water play can communicate. They plan, and tell each Dramatic play with baby doll other what to do. They do things in response and doll equipment, toys for to what others do. They pretend to play housekeeping, play house, be a mother and father, and try out telephone. relationships.
A study was conducted to compare the growth and nutritional status of Indian preschool children for the periods 1998/99 and 2005/06. Using data on weight and length/height as well as the socio demographic background of preschool children from the National Family Health Surveys. The rates of growth of mean weight and length/ height were far lower in India than the international norms up to the age of 7 years. They concluded that the level of mothers education needs urgent attention with top priority to reduce the prevalence of underweight and stunting of children. This also implies that, for future benefit, girls should be given more facilities for better education. Breastfeeding and weaning practices also need special attention.
The adolescent is a time of both change andstability. Adolescence begins with puberty and extends from 12 to 20 years of age.
•Changes in the adolescents body transform him or her from achild to an adult in appearance•Weight and height: rapid increase or spurt and the childbecomes tall. Gain in weight is proportionately greater thangain in height•Dentition: permanent teeth number increases, 2nd molar andcuspid and bicuspid teeth erupt from 10 to 13 yrs,•The feet, hands, and long bones grow rapidly, accompa-niedby an increase in muscle mass (especially in boys).
Puberty It is a short period that overlaps the end of childhood and the beginning of adolescence, time of rapid growth and change,The time when the ability to reproduce begins. occurs at different ages for the boys and girls and for individuals within each sex group. Usually begins at 9 to 13 years of age in girls (with menstruation usually beginning between 10 and 14 years of age) and at 11 or 14 years of age in boys with nocturnal emission. The time needed to complete the changes during the puberty is 2-4 years. There are 3 stages of puberty- the prepubescent, the pubescent and the post pubescent.
The time when pubertal changes take place more rapidly-it is influenced partly by heredity and by environmental factors. 4 major changes in puberty: changes in body size, changes in body proportion, development of primary and secondary sex characteristics. The most rapid growth in body size comes during the year or two before the sex organs begin to function. Changes in body proportion are influenced by the age of sexual maturing. The primary sex characteristics- sex organs grow and develop rapidly during puberty and become functionally mature in approximately in the middle of puberty.
Sebaceous and auxiliary sweat glands become active. Full adult size is reached, although some young men might continue to grow in their 20s
1) A study was conducted to assess the impact of Personality Traits and Educational Identity Formation in Late Adolescents by examining longitudinal associations of Big Five personality traits (i.e., Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness) with dimensions of identity formation (i.e., identification with commitment and exploration in depth) in the domain of education of 485 Belgian late adolescents by using four annual waves of longitudinal data covering a 3-year period. Multivariate growth models revealed that changes in Big Five personality traits were related to changes in identification with commitment and exploration in depth. Cross-lagged panel models uncovered that, except for Openness, all Big Five traits predicted educational identity dimensions. Educational identity dimensions only predicted Neuroticism. In addition, adolescents with higher levels on the personality trait of Conscientiousness faced fewer study delays.
Early adulthood (roughly ages 18 to 45), Mddle adulthood (approximately ages 45to65), and Late adulthood (over 65)
Early adulthood is the first stage of adulthood in which the body physically changes. In this stage, a person may continue to add a bit of height and weight to her teenage frame. The body continues to undergo significant hormonal changes. These changes may make beards grow a bit thicker and the voice to become slightly deeper and richer. This is the period in which women usually have children, so it is the time in which women gain a little weight and finish their full breast development. They experience excellent health, vigor, and physical functioning Their strength, coordination, reaction time, sensation (sight, hearing, taste, smell, touch), fine motor skills, and sexual response are at a maximum
Women undergo menopause a gradual decrease in ovarian function, with subsequent deple-tion of estrogen and progesterone. This change usually occurs between 40 and 55 years of age. -With the cessation of ovu-lation, menstrual periods stop either gradually or abruptly, and many women experience hot flashes, mood swings, and fatigue. -The loss of estrogen also increases the risk for osteo-porosis and heart disease. -Androgen levels diminish slowly; the man may have some loss of sex-ual potency but is still capable of reproduction. -Fatty tissue is redistributed; men tend to develop abdominal fat, women thicken through the middle. -The skin is drier, wrinkle lines appear on the face, gray hair appears, and men may lose hair on the head. -Cardiac output begins to decrease. -Muscle mass, strength, and agility gradually decrease. -Visual acuity diminishes, especially for near vision (presbyopia). -Hearing acuity diminishes, especially for high-pitched sounds.
The Middle Adult ( 40 to 65 years) The middle adult years are generally considered to be ages 40 to 65. This is a period of gradual and individualized change in both physical and psychosocial dimensions. As the average life span increases, most people in this age group still consider themselves young compared with the other population. Visible signs of aging and a heightened awareness of the time left.
Health of the Middle Adult Both acute and chronic illnesses are more likely to occur, and recovery takes longer. This is a result of slower and more prolonged responses to stressors, more pronounced reactions to an illness, and the possibility of more than one illness being present at a time. The leading causes of death in the middle adult year: are motor vehicle crashes, occupational accidents, suicide and chronic diseases. The major health problems are cardio-vascular and pulmonary diseases, cancer, rheumatoid arthri-tis, diabetes mellitus, obesity, alcoholism, and depression.
Adjusting to the Changes ofMiddle Adulthood Various changes can take place during the middle years. These changes include changes in employment; relationships with a spouse; relationships with children who are becoming adults; and relationships with aging parents . Midlife transition might occur in both men and women in their 40s. Employment Middle-aged adults might experience changes in employment. They may opt for a career change and return to school to obtain new knowledge and skills
Increasing numbers of middle-aged adults are self- employed, often working from home. As the 50s approach, questions about retirement and eco-nomic security become more prevalent, with an increased inter-est in the benefits of financial and retirement plans
Spousal Relationships Relationships with ones spouse may change. A husband or wife may develop neg-ative or critical feelings and attitudes as a result of changes in physical appearance, energy levels, or sexual needs and abilities. Dissatisfaction with not achieving career or family goals con-tributes to the stresses placed on the marriage. Extramarital affairs and divorce may result. Widowhood is more likely to occur in the middle years. The loss of a spouse is a major crisis and a threat to ones self-concept as well as a major role change
Relationships with Children and Aging Family Members Middle-aged adults may be caught in a "generation sandwich." Their children are often independent and married, with chil-dren of their own.
