15 month old sleep schedule: Bedtime and nap schedule

At 15 months, many toddlers do well with about 13 hours of total sleep: a minimum of 10 hours at night and 2 - 3 hours during the day. Many are in the middle of the 2-to-1 nap transition: some still need two naps while others are consolidating to one. On a 1-nap schedule, wake windows are typically 5 - 5.5 hours both before and after the nap. On a 2-nap schedule, expect wake windows of 3.25 - 4 hours before the first nap, and 3.75 - 4 hours before the second.

What a day might look like at 15 months

At 15 months, many toddlers are on a 1-nap schedule with wake windows of 5 - 5.5 hours. Here's a sample day based on a 6:30 AM wake. If your child is still on two naps, expect shorter wake windows and a later bedtime.

6:30 AM
Wake for the day · Breakfast
8:30 AM
Morning snack

Nap · ~2.5 hrs (5-hr wake window)

Bedtime routine
7:30 PM
Asleep · (5.5-hr wake window)
Snack timing · Aim to feed toddlers every 2 - 3 hours. Keeping snacks at least 2 - 3 hours from the next meal helps them come to the table hungry enough to eat a full meal.

Total daily sleep
10+ hours at night, 2 - 3 hours during the day.
Note that these are guidelines. What's normal and healthy can vary.

15 month old toddler milestones: Development, growth, speech, language, and more

At 15 months, most toddlers are walking or running independently, stacking blocks, and figuring out how objects are meant to be used. They may try to brush their own hair, for example. Language is expanding: expect 1 - 3 simple words beyond caregiver names, along with gestures, pointing, and the ability to follow simple verbal commands. Cognitively, toddlers this age copy others during play and search for hidden objects they watched you hide. Socially, look for affection like hugs and kisses, clapping when excited, and a strong attachment to primary caregivers.

15-month milestones to watch for

Every baby develops on their own timeline, but here are the milestones most 15 month olds hit. Use it as a gentle guide, not a checklist to stress over.

🤸

Motor

  • Walks or runs independently (some may still be working on first steps)
  • Climbs on a chair to reach things
  • Can feed themselves with fingers, uses spoon with spillage
  • Tries to use objects the 'right' way (e.g., brushing hair with a brush)
🗣️

Communication

  • Says 1 - 3 simple words beyond names for caregivers
  • Points or gestures to ask for something
  • Can identify 1 - 6 body parts
  • Understands and responds to simple verbal commands
👀

Cognitive

  • Copies others during play
  • Searches for objects hidden while watching
  • Uses simple gestures like waving or shaking head 'no'
  • Understands that caregivers provide safety and predictability
💛

Social & Emotional

  • Shows affection through hugging, cuddling, or kissing
  • Claps when happy or excited
  • Has a strong preference for primary caregivers; separation anxiety may persist
  • Plays near other children but not yet with them
Heads up: If many of these milestones haven't shown up, your child seems to have lost a skill they had, or something feels off, reach out to your healthcare provider. Trust your instincts. You know your child best.

Feeding at 15 months

Feeding at 15 months, by the numbers

At 15 months, toddlers eat 3 meals and 2 snacks a day, with water and milk as their primary drinks. Appetite may be variable since growth is expected to slow in a child's second year.

🥛
~16 oz
Cow's milk per day
Whole cow's milk (or fortified non-dairy alternative) is the recommended drink at this age. More than 24 oz can crowd out solid nutrition.
🥣
3 meals + 2 snacks
Solid food daily
Snacks and meals can look a lot alike. There's no need for special "snack" foods.
🧃
≤4 oz
Juice per day (if any)
Limit to 4 oz of 100% fruit juice daily. Water is the ideal additional drink.
🍽️
Picky eating is normal

A dip in appetite and new food refusals are expected in the second year as growth slows. Keep offering variety without pressure. Repeated exposure over weeks, not days, is what expands the menu.
