Best food for babies
 AAP recommendation
4-6 mo 1 yr
exclusive
breastfeeding
breastfeeding +
weaning
regular foods ±
breastfeeding
What is milk?
 87% water and 13% solids
 fats (including essential fatty acids—linoleic, linolenic,
arachidonic)
 proteins (especially caseins and whey proteins)
 carbohydrates (lactose, composed of glucose and galactose)
 minerals and vitamins
 Fresh milk has a pH of 6.7-6.5
 > 6.7 → mastitis
 < 6.5 → colostrum or bacterial activity
Breast vs Bottle
Breast vs Bottle
 More whey → more easily
digested and promotes more
rapid gastric emptying
 Lactoferrin and immunoglobulin
(specifically secretory IgA) →
host defense
 VLCPUFAs, ARA, and DHA →
visual function and
neurodevelopment
 More lipase → superior fat
absorption
 Unabsorbed lactose → softer
stool, more nonpathogenic fecal
flora, and improved absorption of
minerals
 Oligosaccharides that mimic
bacterial antigen ligands →
preventing bacterial attachment
to host mucosa
 Minerals are more bioavailable
(since bound to digestible
proteins)
Breast vs Bottle
Breast is best?
 Advantages to baby
 ready, proper temperature, fresh, clean (Enterobacter sakazakii)
 ↓ incidence or severity of diarrhea, intestinal bleeding, occult melena,
colic, necrotizing enterocolitis
 ↓ incidence or severity of respiratory illnesses, otitis media, UTI,
bacteremia, bacterial meningitis, infant botulism
 ↓ incidence of obesity and overweight, type 1 DM, celiac disease, Crohn
disease, lymphoma, leukemia, food allergy, eczema
 ↓ hospitalizations and infant mortality
 psychological (close and comfortable relationship with the mother)
Breast is best?
 Advantages to mother
 psychological (sense of accomplishment and being essential)
 decreased risk of postpartum hemorrhage
 longer period of amenorrhea
 reduced risk of ovarian and premenopausal breast cancers
 possible reduced risk of osteoporosis
 Advantages to society
 reduced health care costs
 reduced employee absenteeism
Breast is best
When breast is not best
 Transmission of infections
 HIV, HTLV type 1, CMV, rubella virus, hepatitis B
virus (but not C), and HSV (direct contact)
 Transmission of drugs and allergens
 Metronidazole, sulfonamides, antithyroid, lithium,
drugs of abuse, radioactive dyes, anticancer agents,
isoniazid
 Transmission of contaminants (cigarettes,
alcohol)
 Metabolic diseases in the baby
Nutritional issues with breastfeeding

 ↑ phosphorus
 ↓ linoleic acid (half)
 ↓ iron (two thirds)
 ↑ intestinal blood loss
 Why this discussion important?
 Use of skimmed milk recommended between 12-24 months of
age in those at risk of overweight or obesity.

 Use only evaporated milk (not condensed milk)
 All utensils should be sterilized by boiling in
water for 5 to 10 min (rubber nipples for no
more than 5 minutes)
 Quart (32 oz) bottle are easiest to use
 1 can (13 oz) of evaporated milk + tap water + 2
tablespoons of cane sugar

increasingly fussy with feeds. The infant has otherwise been without fever,
vomiting, change in appetite.
 You consider the differential diagnosis for neonatal hematochezia, which
includes swallowed maternal blood, anal fissure, necrotizing enterocolitis,
and milk protein allergy. After initial evaluation, you decide that milk
protein allergy is most likely cause for the hematochezia and recommend
that they switch to which of the following formulas?

Editor's Notes

  • #3 Weaning at 4-6 mo recommended by AAP, WHO, and European Society for Pediatric Gastroenterology, Hepatology, and Nutrition
  • #8 Dynamic nutrient composition that differs throughout lactation, over the course of a day, within a feeding, and among women. Colostrum is the milk produced during the first 3 to 5 days. Its protein content is higher, including immunoglobulins and carotene, and it contains enzymes to stimulate gut maturation. Macrophages in human milk may synthesize complement, lysozyme, and lactoferrin. In addition, breast milk contains lactoferrin, an iron-binding whey protein that is normally about one-third saturated with iron and has an inhibitory effect on the growth of Escherichia coli in the intestine. The lower pH of the stool of breast-fed infants is thought to contribute to the favorable intestinal flora of infants fed human milk vs. formula (i.e., more bifidobacteria and lactobacilli; fewer E. coli), which helps protect against infections caused by some species of E. coli. Human milk also contains bile salt-stimulated lipase, which kills Giardia lamblia and Entamoeba histolytica. Transfer of tuberculin responsiveness by breast milk suggests passive transfer of T-cell immunity.
  • #9 Breast-milk stool. The stools of breast-fed infants are usually yellow, soft, and mild-smelling and typically have the consistency of pea soup. Breast milk stools can also be watery.
  • #10 Formula stool. Infants fed commercial formulas typically have darker, firmer stools than breast-fed infants.
  • #15 Between 15 and 25% of children born to HIV-infected mothers get infected with HIV during pregnancy or delivery, while about 15% of the children get infected through breastfeeding. Ways to decrease transmission: treat breast and infant mouth problems early, exclusively breastfeed for first 3 months, only breastfeed for 6 months. Septicemia, active tuberculosis (before 2 weeks of therapy), typhoid fever, breast cancer, malaria should not breastfeed
  • #17 If the mother is allergic to milk or dislikes it, her diet should be supplemented with 1 g calcium daily. Daily fluid intake should approximate 3 qt. The recommended dose is 1 mg/kg daily of elemental iron. The recommended dose is 0.25 mg daily of fluoride after 6 months.
  • #19 Three possibilities should be excluded before assuming that a mother cannot produce sufficient milk: (1) errors in feeding technique; (2) remediable maternal factors related to diet, rest, or emotional distress; and (3) physical disturbances of the infant that interfere with nursing or with weight gain.
  • #20 Supplemental nursing system (SNS). SNS allows a baby to receive additional nutrients while still breastfeeding and thus provides stimulation to the breast. It does not interfere with breastfeeding technique and latch. The tip of the SNS tubing should protrude past the end of the nipple about a quarter of an inch.
  • #21 Double pumping of the breasts. This is the most efficient and effective way for women to maintain a milk supply when they are unable to breast-feed directly. The pump should initially be set at the minimum setting and gradually increased to a level of comfort for the mother. Milk should be refrigerated and then used within 48 hr. Expressed breast milk can be frozen and used for up to 6 mo. Milk should be thawed rapidly by holding under running tepid water and used completely within 24 hr after thawing. Milk should not be microwaved.
  • #23 Ready-to-feed and concentrated once opened keep in refrigerator for no more than 48 hours. Power once opened keep in powder form in refrigerator for no more than 4 weeks.
  • #24 150 ml/kg/day provides 120 kcal/kg/day needed for growth.
  • #27 football sidelying crosscradle cradle
  • #34 Patients are generally started on a very small daily dose (eg, 4 drops per day of a solution of 10 drops of CM in 10 mL of water) and advanced to a maintenance dose (eg, 150 mL of undiluted CM) over several months. An alternative approach is to combine oral immunotherapy with administration of anti-IgE antibodies. This approach could theoretically decrease the risk of adverse reactions during initial treatment.
  • #36 Some reviewers suggest that early exposure to soy may prevent cancer and heart disease. Some reports suggest phytoestrogens have adverse effects with respect to carcinogenesis, reproductive function, immune function, and thyroid disease. Concerns about aluminum toxicity, the failure to achieve equivalent growth rates and albumin levels consistently and reduced bone mineralization
  • #45 Significant benefits to infant host defense, sensory-neural development, gastrointestinal maturation, and some aspects of nutritional status are observed when premature infants are fed their mothers' own milk. A reduction in infection-related morbidity in human milk-fed premature infants has been reported in nearly a dozen descriptive, and a few quasi-randomized, studies in the past 25 years. Human milk-fed infants also have decreased rates of rehospitalization for illness after discharge. Studies on neurodevelopmental outcomes have reported significantly positive effects for human milk intake in the neonatal period and long-term mental and motor development, intelligence quotient, and visual acuity through adolescence. Body composition in adolescence also is associated with human milk intake in the neonatal intensive care unit. Finally, human milk intake is less associated with the development of the metabolic syndrome than infant formula feeding.

  • #55 WND® 1 and 2 free of non-essential amino acids PFD only contains taurine among the amino acids, a non-protein-building amino acid
  • #57 Hematochezia as a result of milk protein is a non–IgE-mediated allergy. About 30% to 50% of children with non–IgE-mediated allergy to milk protein have continued symptoms when transitioned to soy. A hydrolyzed formula is indicated for this infant. Lactose-free and fat-modified formulas still contain milk protein. Although amino acid formulas could also be used, they are more expensive and thus only indicated when multiple allergies are present.
