Watch for overtiredness cues

Yawning, eye rubbing, staring into space and fussiness are all signs your baby needs sleep. Always respond to tired signs rather than watching the clock rigidly — these schedules are guides, not rules.

Understanding Baby Sleep Schedules

01

What is a Wake Window?

A wake window is the amount of time your baby can comfortably stay awake between sleeps before becoming overtired. Wake windows lengthen as your baby grows — a newborn can only manage 45 minutes awake, while a toddler can handle 5–6 hours. Matching your schedule to your baby’s current wake windows is the single most effective thing you can do for sleep.

02

Why the Last Wake Window Matters Most

The wake window before bedtime is the most important one to get right. Too short and your baby won’t be tired enough to sleep well — too long and they’ll be overtired, which makes settling harder and night waking more likely. Most sleep consultants recommend the last wake window be slightly longer than earlier ones. This tool accounts for that automatically.

03

Schedules Are Guides, Not Rules

No schedule survives contact with a real baby. Illness, teething, developmental leaps and growth spurts all disrupt sleep temporarily — and that is completely normal. Use this schedule as a flexible framework, always responding to your baby’s tired cues first. Read our baby sleep guide for the full picture.

04

Nap Transitions Are the Hardest Part

Moving from four naps to three, three to two, and two to one are the most disruptive periods in baby sleep. Each transition typically takes 2–4 weeks. The ages shown in this tool are averages — some babies are ready earlier, some later. Watch behaviour rather than age to know when your baby is ready to drop a nap.

Frequently Asked Questions

What if my baby won’t nap for as long as the schedule suggests?+
Short naps (under 45 minutes) are very common before 4–5 months and are usually related to sleep cycle maturation rather than anything you are doing wrong. For older babies, short naps often mean the wake window before the nap was slightly too long or too short. Try adjusting by 15 minutes in either direction.
My baby’s wake-up time varies — does that make the schedule useless?+
Not at all. The schedule moves with your baby’s actual wake-up time each day. If your baby wakes at 6am instead of 7am, shift everything forward by an hour — the wake windows stay the same, only the clock times change.
When should I start trying to establish a sleep schedule?+
Most sleep consultants suggest waiting until around 8–12 weeks before introducing any structure, as newborns need to feed on demand and their circadian rhythm is not yet developed. A more consistent schedule typically becomes possible around 4–5 months.
What is a split night and what causes it?+
A split night is when your baby wakes between midnight and 4am and is alert and happy for an extended period. It is usually caused by too much daytime sleep or a bedtime that is too early. Try capping daytime naps or pushing bedtime 20–30 minutes later.
Is it normal for sleep to get worse at 4 months?+
Yes — the 4 month sleep regression is real and is caused by a permanent change in how your baby cycles through sleep stages. It is not a regression that passes — it is a developmental change that requires adjusting your approach. Wake windows become much more important after this point. Read our baby sleep guide for more detail.
