14-15 Month Old Sleep Schedule: Naps, Bedtime & the One-Nap Transition

The Age Where Everything Shifts

Somewhere between 14 and 15 months, your baby starts becoming a toddler in every sense of the word. They're walking (or about to), their language is exploding, and they have opinions about everything — including sleep. If your previously reliable two-nap schedule has started falling apart, you're not alone. This is one of the most common transition points parents navigate.

The big question at this age is almost always the same: is it time to drop to one nap? The answer depends on your baby's signals, not their age. Some 14-month-olds are firmly ready; others need two naps for another few months. Both are completely normal.

Quick answer: Most 14-15 month olds need 12-14 hours of total sleep: 10-11 hours at night plus 2-3 hours of daytime sleep. Many are transitioning from 2 naps to 1, with wake windows of 3.5-4.5 hours.

How Much Sleep Does a 14-15 Month Old Need?

At this age, toddlers need approximately 12-14 hours of total sleep per 24 hours. The typical breakdown is 10-11 hours overnight and 2-3 hours of daytime sleep. The American Academy of Pediatrics recommends 11-14 hours for children aged 1-2 years, and most 14-15 month olds land comfortably in this range.

The amount of awake time your toddler can handle is also increasing. Wake windows of 3.5-4.5 hours are typical, with the longest stretch falling before bedtime. This is what makes the two-nap schedule feel unsustainable — your toddler simply isn't tired enough for two naps anymore.

The One-Nap Transition: When and How

This is the defining sleep challenge of this age. Here's how to tell if your 14-15 month old is ready:

Signs of readiness:

• •Consistently refusing the second nap for 2-3 weeks (not just a few days)
• •Taking 30+ minutes to fall asleep for the second nap
• •The second nap ends so late (after 4:30pm) that bedtime gets pushed past 8pm
• •First nap is getting longer and more restorative

Signs it's too early:

• •Refusing the second nap but then melting down before dinner
• •Short, cranky afternoons that end in tears
• •Night wakings increasing after dropping the second nap

If you're seeing mixed signals, your toddler may be in the transition zone. The approach is to gradually shift to one nap while keeping an early bedtime as a safety net.

Sample Schedules: Two Naps and One Nap

If still on two naps

If on one nap

During the transition (which takes 2-3 weeks), you might alternate: some days your toddler needs two short naps, other days one long one. That's normal. An earlier bedtime (6:30-7:00pm) helps bridge the gap on the harder days.

Common Challenges at 14-15 Months

Bedtime resistance. Your toddler now has the language and willpower to protest. "No sleep!" becomes a regular refrain. The fix is a consistent, predictable routine that doesn't change based on their protests. A bedtime routine of 20-30 minutes — bath, pyjamas, book, cuddle, cot — gives clear signals. Offer limited choices ("Which book? Blue pyjamas or green?") to give them a sense of control.

Night wakings returning. If your toddler was sleeping through the night and suddenly starts waking, check: are they in a cot they can climb out of? Have they recently moved to a toddler bed? Is the room too warm or too cold? Are they dropping a nap and getting overtired? Most night wakings at this age are schedule-related rather than behavioural.

Early morning waking. Waking at 5am is common during the nap transition. If your toddler is waking before 6am consistently, check that bedtime isn't too early (creating too much time in the cot) or too late (causing overtiredness-driven early waking). Blackout curtains and a consistent response to early wakings help.

Climbing out of the cot. If your 14-15 month old is scaling the cot rails, it's time to transition to a toddler bed. This is a safety issue, not a sleep training choice. A floor bed or low toddler bed with a guard rail works well.

When to Talk to Your Pediatrician

Most sleep changes at 14-15 months are developmental and resolve with schedule adjustments. Talk to your doctor if your toddler is snoring regularly, seems in pain during the night, has suddenly stopped eating alongside sleep disruption, or if you have a gut feeling something isn't right.

You've Got This

The 14-15 month mark is a transition zone — your baby is becoming a toddler, and sleep is shifting accordingly. The nap transition can feel unsettling, but it's a sign of healthy development. Stay consistent with your routine, keep bedtime predictable, and trust that this phase will settle.
