Physical development of infants and toddlerhood

  1. 1. PHYSICAL DEVELOPMENT OF INFANTS AND TODDLERS MODULE 12
  2. 2. TODDLERS Young child: a young child who is learning to walk.
  3. 3. CEPHALOCAUDAL  The postnatal growth from conception to 5 months when the head grows more than the body.  The greatest growth always occurs at the top –the head.  The infants learns to use their ‘’UPPER LIMBS ‘’before heir ‘’LOWER LIMBS ‘’.  The same pattern occurs in the head area _.  The top parts of the head= the eyes and the brain- grow faster than the lower parts such as the jaw.
  4. 4. PROXIMODISTAL The pre-natal growth from 5 months to birth when the fetus grows from the inside of the body outwards. The muscular control of the trunk and the arms comes earlier as compared to the hands and fingers. MOTOR DEVELOPMENT  Refers to the development of motor skills from the center of the body outward.
  5. 5. PHYSICAL DEVELOPMENTS HEIGHT & WEIGHT  Its normal for new born babies to drop 5 to 10 percent of their body weight within a couple of weeks of birth.(Due to the baby’s adjustment to neonatal feeding/ once they adjust to sucking, swallowing and digesting, they grow rapidly).  Breastfed babies are typically heavier than the bottle-fed babies through the first 6 months.(After 6 months, breastfed babies usually weigh less than bottle-fed babies.  In general, an infant’s length increases by about 30% in the first 5 months.  A baby’s weight usually triples during the first year but slows down in the second year of life.  Low percentages are not a cause for alarm as long as infants progress along a natural curve of steady development.
  6. 6. Brain Development Among the most dramatic changes in the brain in the first 2 years of life are the spreading connections of dendrites to each other. (Remember neurons, dendrites, axon, synapses). Myelination or myelinization =The process by which the axons are covered and insulated by layers of fat cells, begins prenatally and continues after birth. =The process of MYELINATION or MYELINIZATION increases the speed at w/c information travels through the nervous system.
  7. 7.  At birth, the newborn’s brain is about 25% of its adult weight. By the second birthday, the brain is about 75% of its adult weight.  Shortly after birth, a baby’s brain produces trillions more connections between neurons than it can possibly use. The brain eliminates connections that are seldom or never used. The infant’s brain is literally waiting for experiences to determine how connections are made.
  8. 8. Motor Development Along this aspect of motor development, infants and toddlers begin from reflexes, to gross motor skills and fine motor skills. REFLEXES  The newborn has some basic reflexes which are, of course automatic, and serve as survival mechanisms before they have the opportunity to learn. Many reflexes which are present at birth with generally subside within a few months as the baby grows and matures. COMMON REFLEXES  Sucking Reflex( The sucking reflexes is initiated when something touches the roof of an infant’s mouth. Infants have a strong sucking reflex which helps to ensure they can latch unto bottle or breast. The sucking reflex is very strong in some infants and they may need to suck on a pacifier for comfort).  Rooting Reflex( The roofing reflex is most evident when an infant’s cheek is stroked. The baby responds by turning his or her head in the direction of the touch and opening their mouth for feeding).
  9. 9.  Gripping Reflex( Babies will grasp anything that is placed in their palm. The strength of this grip is strong, and most babies can support their entire weight in their grip).  Curling Reflex( When the inner sole of a baby’s foot is stroked the infant respond by curling his or her toes. When the outer sole of a baby’s foot is stroked, the infant will respond by spreading out their toes).  Startle/Moro Reflex( Infants will respond to sudden sounds or movements by throwing their arms and legs out, and throwing their heads back. Most infants will usually cry when startled and proceed to pull their limbs back into their bodies ).  Galant Reflex( The galant reflex is shown when an infant’s middle or lower back is stroked next to the spinal cord. The baby will respond by curving his or her body toward the side which is being stroked).  Tonic Neck Reflex( The tonic neck reflex is demonstrated in infants who are placed on their abdomens. Whenever side the child’s head is facing, the limbs on that side will straighten, while the opposite limbs will curl).
  10. 10. LIFE SPAN DEVELOPMENT OF INFANTS and TODDLERS
  11. 11. Gross Motor Skills  It is always a source of excitement for parents to witness dramatic changes in the infant’s first year of life. This dramatic motor development is shown in babies unable to even lift their heads to being able to grab things off the cabinet, to chase the ball and to walk away from parents. Fine Motor Skills  Are skills that involve a refined use of the small muscles controlling the hand, finger and thumb. The development of these skills allows one to be able to complete tasks such as writing, drawing and buttoning.  The ability to exhibit fine motor skills involve activities that involve precise eye- hand coordination.  The development of reaching and grasping becomes more refined during the first 2 years of life. Initially, infants show only crude shoulder and elbow movements, but later they show wrist movements, hand rotation and coordination of the thumb and forefinger.
  12. 12. SENSORY and PERCEPTUAL DEVELOPMENT  The newborn senses the world into which he/she is born through his/her senses of vision, hearing, touch, taste and smell. As he/she advances physically his/her sensory and perceptual abilities also develop.
  13. 13. RESEACH FINDINGS regarding NEWBORN’S VISUAL PERCEPTION  The newborn’s vision is about 10 to 30 times lower than normal adult vision. By 6 months of age, vision becomes better and by the first birthday, the infant’s vision approximates that of an adult.  Infants look at different things for different lengths of time. In an experiment conducted by Robert Fantz(1963 cited by Santrock, 2002), it was found out that infants preferred to look at patterns such as faces and concentric circles rather than at color or brightness. Based on these results, it is likely that ‘’pattern perception has an innate basis’’. Among the first few things that babies learn to recognize is their mother’s face, as mother feeds and nurses them.
  14. 14. Can NEWBORN Hear?  The sense of hearing in an infant develops much before the birth of the baby. When in the womb, the baby hears his/her mother’s heartbeats, the grumbling of his/her stomach, the mother’s voice and music.  Infants’ sensory thresholds are somewhat higher than those of adult which means that stimulus must be louder to be heard by a newborn than by an adult.
  15. 15. Can NEWBORNS differentiate Odors?  In an experiment conducted by MacFarlane(1975) ‘’ Young infants who were breastfed showed a clear preference for smelling their mother’s breast pad when the babies were only two days old. This shows that it requires several days of experience to recognize their mother’s breast pad odor’’. Can NEWBORNS feel pain?Do they Respond to touch?  They do feel pain. Newborn males show a higher level of cortisol( an indicator of stress) after a circumcision than prior to the surgery.  Babies respond to touch. The newborn automatically sucks an object placed in his/her head toward the side that was touched in an apparent effort to find something to suck.
  16. 16. Can NEWBORNS distinguish the different tastes?  In a study conducted with babies only two hour old, babies made different facial expressions when they tasted sweet, sour and bitter solutions.  When saccharin was added to the amniotic fluid of a near-term fetus, increased swallowing was observed.  This indicates that sensitivity to taste might be present before birth. Do infants relate information through several senses? Or Are infants capable of intermodal perception?  INTERMODAL PERCEPTION is the ability to relate, connect and integrate information about two or more sensory modalities such as vision and hearing.  In a study conducted by Spelke and Owsley(1979), it was found out that as early as at 3 ½ months old, infants looked more at their mother when they also heard her voice and longer at their father when they also heard his voice.  This capacity for intermodal perception or ability to connect information coming through various modes gets sharpened considerably through experience.
