Is waking at 5am normal for a baby?
Anything from 6am is a normal biological wake time for most babies, frustrating as that is. Before 6am is an early waking — and the defining feature is that your baby wakes unfinished: grumpy, rubbing eyes, clearly still tired, but unable to get back to sleep. That last part is the clue: at 4–5am, sleep pressure is nearly spent and the sleep drive is at its weakest, so anything — light, a habit, a schedule mismatch — is enough to end the night.

What causes early morning wakings?
The counterintuitive one first: overtiredness. A baby who goes to bed overtired sleeps less well and wakes earlier — so the instinct to push bedtime later usually makes 5am worse, not better. Then the schedule: a bedtime mismatched to the last nap, wake windows that don't fit, or a morning nap so early it functions as the missing end of the night, teaching the body that waking at 5 works. And finally the environment: from 4am, sleep is fragile enough that summer light through a blind or a neighbour's car door can end the night.

Can bedtime cause early wakings?
Yes — and in both directions, which is why generic advice fails here. Too late a bedtime creates overtiredness that ends the night early; but too early a bedtime can also produce early wakings, simply because a baby who needs eleven hours and sleeps at 6pm is done at 5am. The right bedtime sits in a fairly narrow window that depends on your baby's age, their last nap, and their total sleep need — and small shifts of 15–20 minutes, held for several days, often move the morning more than any other change.
Is the morning nap making it worse?
Often, yes — this is the lock that keeps the cycle closed. A 7am nap after a 5am wake isn't really a nap; it's the end of the night, relocated. The body learns the split and repeats it. Gently pushing that first nap later, in small steps, is usually part of the fix — it rebuilds the pressure to sleep through to a normal wake time. (the relevant nap/schedule article)
How do I fix early morning wakings?
In this order: make the room genuinely dark (blackout that survives a summer sunrise) and check for early-morning noise. Then fix the day: age-appropriate wake windows, a protected last nap, and a bedtime matched to it — earlier if overtiredness is driving it, slightly later only if the schedule genuinely shows too much night sleep. Then hold steady for a week: respond at 5am with minimal stimulation, no lights, no fun, breakfast never before a set time — mornings change slowly, and consistency is what moves them. Early wakings are almost always the last thing to resolve, so if nights and naps are improving, the mornings are coming.
