Progressing from a fully liquid diet to the mixed diet of “family foods” occurs between approximately 6 and 24 months of age.
Assess
- Anthropometric measurements
- Physical examination
- Adequacy of human milk or formula intake
- High-protein intakes from formula and complementary foods may be a risk factor for excessive infant weight gain; recommendations have been proposed (though not yet made) to limit total protein to 15% of energy intake.
- Iron intake
- If iron intake is inadequate, especially for breastfeeding infants, then supplements of iron should be continued (1 mg/kg/d).
- Research indicates that the complementary foods of more than 50% of infants in the United States do not meet iron requirements; this applies to more than 95% of breastfed infants.
- Screen for food insecurity using the validated 2-question Hunger Vital Sign tool
- 1 in 7 children live in a household experiencing food insecurity
- Rates of food insecurity are higher in households with children younger than 6 years; single parent households; and immigrant, Black or Latinx families
- Provide resources for families experiencing food insecurity. (Table 3)
Discuss
- Begin complementary foods from all groups, emphasizing sources of iron.
- Encourage baby-led weaning and offer soft, bone-free versions of whatever the family is eating at meals.
- Encourage sitting at the table with the family for meals and use of all 5 senses to explore food.
- Encourage a wide variety of healthy iron-rich foods, including starches, meats, fruits, and vegetables.
- At this stage, infants are simply exploring new tastes and textures, which encourages them not to be picky eaters later in life.
- Continue vitamin D at 400 IU/day.
- If bottle-feeding, advise not to put baby in bed with a bottle (for a nap or the night).
- Avoid honey.
- If infants are weaned from breast before 12 months, iron-fortified formula should be used.
- There is little evidence that partially or extensively hydrolyzed formula prevents atopic disease, even in high-risk infants.
- Avoid soy milk, cow milk, and goat milk before 12 months of age, unless medically indicated.
- Limit whole milk to <16 oz per day.
- Avoid juice.
- Continue breastfeeding.
Calculations
Estimated energy requirements (kcal/d) for infants 6 months to 2.99 years (weight in kg; height in cm):
- Males: −716.45 − (1.00 × age) + (17.82 × height) + (15.06 × weight) + 20
- Females: −69.15 + (80.0 × age) + (2.65 × height) + (54.15 × weight) + 20/15
- Energy cost of growth for girls: 6 to 11.99 months: 20 kcal/d; 12 to 35.99 months: 15 kcal/d.
