Here is a complete, evidence-based answer:

Feeding a 6-Month-Old When Breastfeeding is Not Possible

At 6 months, a baby is at a natural transition point: even with full breastfeeding, breast milk alone can no longer meet all nutritional needs. When breastfeeding is not possible at all, the approach combines infant formula as the milk substitute with the start of complementary solid foods.

1. Primary Milk Substitute: Infant Formula

  • Commercial iron-fortified infant formula is the first-choice substitute for breastmilk in infants 6-11 months of age, wherever it can be safely prepared (clean water, proper storage).
  • Animal milk (cow's milk, boiled) is an acceptable alternative at 6+ months if formula is not available - but it is not ideal as a main drink under 12 months because it is lower in iron and has too much protein.
  • Follow-up formulas (Stage 2/3) are generally not recommended - standard infant formula is sufficient.
  • Avoid regular cow's milk as the main drink under 12 months; small amounts used in cooking or mixed with foods are fine.
How much formula? At 6 months, approximately 500-700 mL (17-24 oz) per day, split into 4-5 feeds.

2. Start Complementary (Solid) Foods at 6 Months

At 6 months, all babies - breastfed or not - should begin solid foods. For a non-breastfed baby this is even more important to fill nutritional gaps.

Signs of readiness (all three must be present):

  • Sits with support, good head/neck control
  • Opens mouth for food and reaches for it
  • Swallows food rather than pushing it back out with the tongue

What to give - by priority:

Food GroupExamplesWhy Important
Iron-rich foods (top priority)Pureed/minced meat, chicken, fish, liver; well-cooked egg yolk; lentils/beans; iron-fortified cerealPrevents iron deficiency anemia - critical at this age
VegetablesPureed carrot, sweet potato, squash, peas, spinachMicronutrients, fiber
FruitsMashed banana, avocado, cooked pear/appleEnergy, vitamins
Starchy staplesRice porridge, mashed potato, soft cooked oatsEnergy
DairyYogurt, soft cheese (not cow's milk as main drink)Calcium, protein

How to feed:

  • Start with 1-2 teaspoons per sitting; gradually increase over days/weeks
  • Texture: smooth purees and mashes at 6 months; progress to lumpier textures by 8-9 months; "finger foods" by 8 months
  • Frequency: 2-3 times/day at 6-8 months; increase to 3-4 times/day at 9-11 months
  • Never force-feed; follow the baby's hunger and fullness cues

3. Key Nutritional Considerations

  • Iron: Most critical nutrient. The WHO guideline stresses daily animal-source foods (meat, fish, or eggs) because iron from plant foods alone is insufficient.
  • Vitamin D: Supplement with 400 IU/day if formula intake is less than 1 liter/day (formula-fed babies getting >1L already get enough from the formula).
  • Vitamin B12: If diet is vegetarian/vegan, a supplement is needed - B12 gaps appear in non-breastfed babies not eating meat/eggs.
  • Zinc: Covered by meat, eggs, and legumes.

4. What NOT to Give

  • Honey (risk of infant botulism under 12 months)
  • Cow's milk as the main drink under 12 months
  • Sugary drinks, juice, soda, tea
  • Whole grapes, raw hard vegetables (choking hazard)
  • Highly salted or sweetened foods
  • Soy milk, almond milk, oat milk - these are NOT nutritionally adequate substitutes for infant formula

5. Special Situations

SituationRecommendation
Low-resource setting, no access to formulaBoil animal milk; give mixed diet with iron-rich foods; consult health worker for micronutrient supplements
Allergy to cow's milk proteinUse extensively hydrolyzed or soy-based formula (on medical advice)
Donor human milkWHO endorses pasteurized donor human milk as second best after own mother's milk, where available

The bottom line: At 6 months, iron-fortified infant formula replaces breast milk as the main drink, and solid foods are introduced simultaneously starting with iron-rich purees (meat, egg, lentils), then vegetables and fruits. Formula remains the primary source of nutrition until 12 months, with solids gradually increasing. Always ensure clean preparation of formula and consult a pediatrician or health worker for the specific brand and amount suited to the baby's weight.
