While breast milk is recommended for most infants during the first 6-12 months of life or longer, formula is often used in infancy when breast milk is not available or contraindicated. Formula is also given to older children who are unable to obtain adequate nutrition through conventional means. This page informs clinicians about the different types of formulas for premature infants, term infants, and older children and includes information about adjusting caloric density and selecting different formula types. For ideas about obtaining financial help with purchasing formulas for children with special health care needs, see Affording Formula.

Formula Basics

Formula comes in 3 different forms:

Ready to feed (does not need to be prepared with water)
Powdered (must be mixed with water, but is the least expensive form)
Concentrated liquid

Formulas are made of 6 basic components - protein, fat, carbohydrate, vitamins, minerals, and other nutrients. Details about the components that make up formula can be found on the Portal at Formula Ingredients and Components. What makes formulas unique are the specific carbohydrates, fats, and proteins used, as well as any additional ingredients added. These differences and their indicated use are explained below. International recommendations for formula composition can be found at [Koletzko: 2005].

Delivery of formula can involve use of a cup, spoon, supplemental nursing system, bottle, or feeding tube (see Feeding Tubes & Gastrostomies in Children). The nutritional content of formula is regulated by the U.S. Food & Drug Administration based on recommendations by the Committee on Nutrition (AAP). Nutritional requirements, digestive concerns, metabolic demands, and the child's age drive the selection of one formula over another. Background information on the many types of formulas available and detailed information about the different components of formula and the rationale for their use are presented below.

The links, below, lead to charts that list the major brands of formula and key differences among their ingredients. The Medical Home Portal does not endorse a specific brand or preparation; but, commercially prepared formulas will be mentioned here to provide examples.

Formula for Term Infants

Infant formulas provide for the nutritional needs of most non-breastfed infants less than 1 year old. Standard formulas contain 20 Kcal/oz and 0.45 grams of protein/oz. [National: 2015] Formulas based on cow milk are appropriate for most full-term and preterm infants. The AAP recommends that all infants be fed breast milk or iron-fortified formula for at least 12 months. First year weight gain goals for most term infants are as follows:

First Year Weight Gain Goals (Birth-12 Months) for Term Infants


Age	Grams/Day
0-3 months	25-30
3-6 months	15-20
6-12 months	10-15

[Committee: 2013]

Infants with increased energy needs, a history of postnatal growth restriction, or feeding difficulties may continue on a higher caloric density feeding (24 kcal/oz). [Laili: 2010] After hospital discharge, it is unclear what represents optimal growth for the preterm infant. Growth data should be plotted according to the infant’s age corrected for prematurity.

Major brands of formula and key differences among their ingredients are listed below. The Medical Home Portal does not endorse a specific brand or preparation; but, commercially prepared formulas will be mentioned here to provide examples.

Formulas for Term Infants ( 265 KB)

Formula for Preterm and Low Birth Weight Babies

Increased calorie infant formulas:

Indications for use: Infants with low birth weight and preterm infants
Examples: Similac Neosure Advance 22 kcal/oz, Enfamil Enfacare LIPIL 22 kcal/oz, Similac Special Care Advance 24 kcal/oz, Enfamil Premature LI PIL 24 kcal/oz

Recipes for increasing caloric density using standard 20 kcal/oz and 22 kcal/oz formulas are provided below.

Preterm formulas:

Indications for use: Formulated for preterm infant specialized nutritional needs, which include increased protein, certain vitamins and minerals (such as calcium and phosphorus), and carbohydrates and fats designed to promote absorption (including a substantial portion of medium chain triglycerides). [Committee: 2013]
Examples: Similac Neosure Advance 22 kcal/oz, Enfamil Enfacare LIPIL 22 kc al/oz, Similac Special Care Advance 24 kcal/oz, Enfamil Premature LI PIL 24 kcal/oz

Human milk fortifiers:

Indications for use: Formulated to improve metabolic outcomes in preterm infants whose primary long-term nutritional source is breast milk, to supply adequate protein, sodium, zinc, and to facilitate bone development. Liquid or powder formulations are added to breast milk. Human milk fortifiers may be found in the hospital setting; outside of the hospital setting, they typically require a prescription.
Examples: Similac Human Milk Fortifier, Prolact Human Milk Fortifier, Enfamil Human Milk Fortifier

Formula for Older Children

Usually after age 1, children requiring supplemental or complete nutrition from a formula are changed from an infant formula to one designed to give a better balance of nutrition for the older child. Although childhood formulas are recommended for children ages 1-10, it may be appropriate to continue some teenagers, especially those with severe disabilities, on these formulas because they provide a better ratio of protein to overall calories. The energy and nutrient requirements of adolescents with special health needs vary according to their individual metabolic rate, activity level, and medical status. The child or adolescent should routinely be monitored to ensure adequate nutrition for growth and development and to make adjustments during periods of stress and illness.

Increasing Caloric Density - General Guide

Important recipes for increasing caloric density: When infants need extra calories to grow, the medical team can provide recipes for increasing the calories of 20 kcal/oz formulas ("term" formulas), or for 22 kcal/oz formulas (“preterm” formulas).
Advise the caregiver to use precise measurements (e.g., a level scoop rather than rounded) to ensure consistent nutrition. Consult a dietician if unfamiliar with the nutritional and/or fluid requirements of your patient. If needed, contact a local NICU or children's hospital for advice. Cost and ease of home preparation must be considered.
Using Term Powder Formula to Increase Caloric Density


kcal/oz	Add one scoop of 20 kcal/oz powder formula to:
20	60 mL or 2 oz of water
22	55 mL of water
24	50 mL of water
26	45 mL of water
27	42 mL of water

+ Due to variations in formula composition, it is best to consult the manufacturer's website for more details. Powder is less accurate than liquid concentrates. [American: 2013]
Using Preterm Powder Formula to Increase Caloric Density for Preterm Feeding Infants


kcal/oz	Add one scoop of 22 kcal/oz premature infant powder formula to:
22	60 mL or 2 oz of water
24	55 mL of water
26	50 mL of water
27	48 mL of water

Do-It-Yourself Formulas

The American Academy of Pediatrics advises against making home-made infant formula due to serious risks of infection, ingredients that may be aspirated, and intolerance, as well as incomplete nutrition or excessive loads of certain ingredients that may be toxic. However, families may be very interested in learning more about this topic. One site with extensive information is Do-It-Yourself Baby Formulas, which is based on Weston A. Price Wise Traditions in Food, Farm, and the Healing Arts whole foods approach to diet.

Many families of children with special health needs also develop blenderized diets for tube feeding. These consist of taking a wholesome diet and blending it into a consistency that can be administered through a feeding tube. Consulting with a dietician is advised for families who wish to pursue blenderized feeding instead of, or in addition to, formula.

Brands of Formulas

Parents often ask their doctor for advice about brands. The following links lead to charts that list many brands of formula and key differences among their ingredients. The Medical Home Portal does not endorse a specific brand.

Although infant formulas are required to meet the requirements of the Infant Formula Act, manufacturers’ marketing claims often are not supported by clinical evidence or evaluated by the Food and Drug Administration. [Belamarich: 2015] FDA approval is only required for claims regarding formulas and their relationship to medical conditions; claims that do not reference conditions or disease (e.g., probiotics support digestive health) do not need FDA approval. [Abrams: 2015] Insufficient evidence shows that removing or reducing lactose, using hydrolyzed or soy protein or adding pre-/probiotics to formula benefit infants with fussiness, gas, or colic; [Thomas: 2010] [Sung: 2018] however, ongoing research suggests that various combinations of these may provide benefit for certain conditions such as constipation and prevention of eczema.

Examples of store brands, most of which are manufactured by Perrigo Nutritionals, are:

Babies"R"Us
Berkley Jensen (BJ's)
Comforts for Baby (Kroger)
CVS Health
Kirkland Signature (Costco)
Meijer (Meijer Baby)
Member's Mark (Sam's Club)
Parent's Choice (Walmart)
Simply Right (Sam's Club)
Up & Up (Target)
Well Beginnings (Walgreens)

Pearls and Alerts

When to stop preterm formula
Preterm infant formula and human milk fortifiers are designed to meet the increased vitamin and mineral needs of the preterm infant consuming smaller volumes than the term infant. Continuation of preterm infant formulas and human milk fortifiers in infants who weigh more than 2.5-3.0 kg will result in increased intakes of several vitamins, including vitamins A and D. Case reports of hypervitaminosis D suggest that these products should be discontinued when the infant is exceeding the recommended intakes for fat-soluble vitamins.
Formula feeding contraindications
Contraindications include vomiting or spit-up associated with inadequate weight gain, colic, constipation or diarrhea, blood or mucus in stool, severe or difficult to treat eczema, hives, and anaphylaxis.
Aluminum toxicity
Preterm infants and infants that were intrauterine growth restricted who use soy formula may be at risk of aluminum toxicity. [Fanni: 2014]
