13–15 Months Baby: Milestones, Sleep & Feeding Guide

This period marks the full transition into toddlerhood. Walking is now established and babies are testing independence enthusiastically. Language is accelerating, with a vocabulary of 5-20 words by 15 months. Toddlers begin to understand 'mine' and assert themselves, which can lead to early power struggles. Feeding expands to include almost all family foods.

Highlights

  • Walking confidently with improving balance
  • Vocabulary of 5-20 words by 15 months
  • Points to body parts when asked
  • Understands and follows two-step instructions
  • Begins showing empathy toward others

Feeding at 13–15 Months

What to feed:

  • Whole milk (16-24 oz/day)
  • All soft table foods
  • Family meals in appropriate texture
  • Protein at each meal
  • 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

Schedule: Structured meal and snack times with water between

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)
  • Excessive cow's milk (more than 24 oz crowds out solid food)
  • Added sugar and salt
  • Fruit juice
  • Pressuring or bribing to eat
