Why Is My Baby Waking Up at 5 a.m.? And What Can I Do?

You hear your baby on the monitor, roll over to check the time, and think, Please tell me it’s at least six. Nope. It’s 5:00 a.m. Again.

If your baby keeps waking up at 5 a.m., I get why you want to know what to do in the moment. After hours of sleep, your baby has less drive to drift off again, and they may be starting to get hungry. That’s why, when a family comes to us at Sleep Baby Consulting with early-morning wake-ups, one of the first things I ask is what bedtime looks like.

If your baby needs help falling asleep, start at bedtime

Maybe you rock your baby until they’re asleep, or they usually drift off while feeding. Those can be sweet parts of your evening. If your goal is for your baby to get back to sleep on their own in the early morning, give them a chance to practice falling asleep at bedtime first.

Think about what you’re asking of them at 5:00 a.m. They’ve already slept for hours, so they’re feeling less of that pull toward sleep. They may be starting to get hungry. And now they’re trying to do something on their own that they usually do with your help. That’s a big ask for the hardest part of the night.

At bedtime, your baby has had time to build up sleep pressure since their last nap. That natural drive to sleep makes bedtime a better place to practice. And if your baby is hungry at 5:00 a.m., go ahead and feed them. Feeding your baby when they need it fits right alongside working on bedtime.

Why do babies wake up early between 4 and 6 a.m.?

Your baby’s sleep comes in cycles. In early infancy, a cycle lasts roughly an hour, and that pattern changes as babies grow. Babies can stir or briefly wake as they move through these cycles. As sleep patterns mature, more deep sleep tends to happen earlier in the night, and stretches of REM sleep tend to get longer toward morning. The timing varies with your baby’s age and when they fell asleep. [1, 2, 3]

Here’s where sleep pressure comes in. It builds while your baby is awake and eases as they sleep. If your baby fell asleep at 7:00 p.m., they’ve had up to ten hours of sleep by 5:00 a.m. They may still need more, but the drive to fall back asleep is weaker than it was at midnight. Their body clock is also getting closer to its usual wake time. So the little stir you barely noticed at midnight might turn into an eyes-wide-open wake-up at 5:00 a.m. [1, 4]

Why early-morning wake-ups are often the last to improve

At Sleep Baby Consulting, we use our Sleep Skills Pyramid to help families work through five skills:

Falling asleep independently at bedtime
Getting back to sleep after waking overnight
Falling asleep independently at the start of a nap
Connecting sleep cycles to take a longer nap
Getting back to sleep after an early-morning wake when your baby still needs more sleep

We often hear from parents whose babies are falling asleep on their own, getting back to sleep overnight, and taking longer naps, yet still waking at 5:00 a.m. Early mornings are often the last to improve because your baby is using a skill they’ve been practicing at a time when their body is giving them less help.

What to do when your baby keeps waking up at 5 a.m.

If bedtime is going well and the early wakes are still happening most days, take a look at a few days together. When did your baby actually fall asleep? How long were their naps? Do they wake up hungry? Does the room start getting light or noisy around that time? Those details help us figure out what to look at first.

In the moment, if your baby is comfortable and just stirring, give them a moment to see if they settle. If they need a feed, a diaper change, or comfort, go ahead and help them. Keep the room dim and your voice quiet if you’re hoping they’ll go back to sleep. For newborns and young babies, follow your pediatrician’s feeding guidance. [5]

If you’re reading this after another early start, here’s where I’d begin tonight. If your baby still needs your help to fall asleep, start with bedtime. And if bedtime is already feeling easier, give yourself credit for that progress. In our work with families, that 5:00 a.m. wake is often the piece that takes the longest.
