Baby Sleep

My baby wakes fully at 4-5am and won't resettle - is this normal and how do I fix it?

Early-morning waking (around 4-5am) is very common and is often driven by overtiredness, a bedtime that's too late, too much or poorly timed daytime napping, or early morning light. Babies need roughly 12-16 hours of sleep per 24 hours. Adjusting to an earlier, calmer bedtime, balancing naps, and darkening the room usually helps, though sleep also shifts a lot during developmental leaps.

💡Quick Answer

  • Early waking is often caused by overtiredness, not too much sleep
  • Try an earlier, calmer bedtime and check the last nap isn't too late
  • Aim for roughly 12-16 hours total sleep per 24 hours
  • Darken the room and use white noise to block early light and sound
  • Expect disruption during developmental leaps and growth spurts
  • A loose routine helps more than a rigid schedule at this age

⚠️ Caution:Every baby is different and sleep changes rapidly in the first year. This is shared experience, not medical advice - if early waking comes with feeding problems, distress, or you're severely sleep-deprived, talk to your paediatrician.

🤔What Parents Worry About

Exhausted parents assume an early-rising baby is simply getting enough sleep, when the real cause is often overtiredness making things worse. The reassurance is that small tweaks - earlier bedtime, balanced naps, a darker room - often help, and that disrupted sleep during leaps is temporary and normal.

Here's what moms in our community shared based on their own experience.

  1. 1

    Sometimes early wake-ups are because of overtiredness, not too much sleep. An overtired baby actually sleeps worse and wakes earlier. Try an earlier, calmer bedtime and watch that the last nap isn't too close to bedtime.

  2. 2

    At this age it's all still changing so much. They also go through developmental leaps and growth spurts that disrupt sleep for a while. Generally total sleep should be somewhere between 12-16 hours per 24 hours, so that gives you a rough idea to work towards.

  3. 3

    Following a loose routine helped my sanity - just having an idea of where to aim, then adjusting to what my baby actually needed. A dark room and white noise made early-morning wakes less frequent for us.

  4. 4

    Solidarity - some babies just fight sleep by nature. Letting her sleep when she gives cues and not forcing a rigid schedule too early is okay. It does pass, even if it's exhausting right now.
