Feeding at 13–15 Months
What to feed:
- Whole milk (16-24 oz/day)

- Fruits and vegetables at every meal
- Whole grains
How much: Three meals and two snacks; toddler servings are about 1/4 of an adult portion

Feeding Tips
- Toddlers eat well one day and refuse food the next - this is normal
- Division of responsibility: you decide what and when; toddler decides if and how much
- Make mealtimes pleasant and social without pressure
- Offer familiar and new foods at the same meal
- Healthy grazing between meals reduces mealtime appetite - use structured snack times
Foods to Avoid
- Whole grapes, hot dogs, large pieces of raw vegetables (choking risk)

- Fruit juice
- Pressuring or bribing to eat
