First and Foremost
“Breast milk is the optimal source of nutrition for the infant but, when breast milk is not available, iron‐fortified infant formula is an appropriate alternative for the infant’s
first year of life.”
Hierarchy1. Mother’s own milk/colostrum
2. Pasteurized donor banked human milk
3. Hypoallergenic infant formula
4. Elemental infant formula
5. Bovine milk based infant formula
6. Soy infant formula
7. Water/Glucose Water
Regulation of Infant Formula
3
The Food, Drug, and Cosmetic Act
• Mandates all infant formulas marketed in the US provide the same nutrition for healthy, full‐term infants
Formulation
In comparison to breastmilk:
• Lower in fat
• Higher in carbohydrate, protein, and minerals
48‐50% Fat
40‐45% CHO
9% PRO
4
Iron‐Fortified
DHA/ARA
• In breastmilk
• Added to infant formula in the US early 2002
• No official position by AAP
• Long‐Chain Polyunsaturated Fatty AcidsoARA = Arachidonic Acid (n‐6)
oDHA = Docosahexanoic Acid (n‐3)
• Major fatty acids in the brain and retina
Nucleotides, Prebiotics, Probiotics
• Nucleotides:oBuilding blocks of RNA, DNA, and ATP
o Present in breast milk
oMay enhance immune function and healthy development of GI tractwhen added to formula
• Prebiotics support growth of good bacteria in the intestine
• Probiotics = nonpathogenic bacteria
5
Navigating the Options
Forms• Powders
o Least expensive
o Important to follow mixing directions (water to powder)
• Liquid concentratesoMore expensive than powders
oAlso important to follow mixing directions (water to concentrate)
• Ready‐to‐useo Typically most expensive
oNo mixing
6
Formula Preparation
Special Concerns
• Powdered infant formulas are not commercially sterileoHeat‐treated during processing, but unlike liquid products, not subjected to high temperatures for sufficient time to make the final product commercially sterile
• FDA Alert (2002) ‐ Enterobacter Sakazakii (E. Sakazakii)oMicroorganism
oMay cause sepsis, meningitis, or necrotizing enterocolitis
o Premature infants or medically compromised at highest risk
Water
• Ensure safe water source
• If in doubt about water supply or in case of water contamination in community find alternative clean water source
• Sterilize water by bringing to boil, boil 1‐2 minutes, then cool

Milk‐Based Formulas
Examples:
oSimilac Advanced
oEnfamil
oGood Start
• Most common
• Casein is predominant protein (vs whey in human milk)
o Some altered to contain more whey
• Iron‐Fortified
Soy‐Based Formulas
• Examples:
o Isomil
o Prosobee
oGoodstart Soy
• Developed for infants who cannot tolerate cow’s milk formula
• Ingredients:
o soybean solids (protein)
o vegetable oils
o carbohydrates (usually sucrose and/or corn syrup solids)
o vitamins and minerals
Soy‐Based Formulas, Cont.
May be indicated for:
• Galactosemia
• Parents seeking a vegetarian diet for their full‐term infant
• IgE‐mediated allergy tocow’s milk protein
Not recommended for:
• Acute gastroenteritis
• Infants with colic
• Prevention of allergy
• Non‐IgE‐associated allergy symptoms: Diarrhea, malabsorption, colitis, esophagitis
8
Lactose‐Free Formulas
• Lactose is major carbohydrate in cow’s milk based infant formula
• Very small number of infants produce insufficient amounts of lactase, the enzyme needed to break down lactose
Hypoallergenic/Elemental Formulas
Examples:
o Alimentum
o Elecare
o Gentlease
o Nutramigen
o Pregestimil
o Neocate
• Partially or Extensively hydrolyzed protein
• Infants with non‐IgE‐associated symptoms
• Strong family history of allergy
• May also use elemental formula (free amino acid‐based formula)
• Some are lactose‐free
• Significantly more expensive
• Altered taste
Increased Calorie Prep
• Only if prescribed by healthcare provider
• Help mom to get information:
oHow long
oWhen to follow up withprovider

Responding to Caregivers Concerns
Changing Formulas
• See healthcare provider for any of the following:oVomiting
oDiarrhea
oAbdominal Pain
oRash
oBlood in the Baby's Stools
• Changing formulas should be done under the supervision of healthcare provider or Registered Dietitian
Feeding Frequency and Amount
• Newborns 8‐12 feedings/24‐Hours
• Start with 2 ounces every 2‐3 Hours
• Partially breastfed/formula‐fed infant may consume less
• Frequency and amount will shift at 6 Months

Organic?
• AAP No Position
• FDA recognizes sucrose as‘safe and well established’
