What to Expect When It Comes to Baby Sleep
If you’ve ever found yourself Googling “how much sleep should a baby get?” in the middle of the night, you’re not alone. One of the biggest surprises for many parents is just how unpredictable baby sleep can be. You might feel like you’ve finally found something that works, only for it to change again a few days later. That has definitely been my experience with all three of my children.
All three of mine struggled with sleep in different ways, partly due to tongue-tie issues, and one thing I learned quickly is that nothing stays the same for long. With my third, I even worried that she was sleeping too much in the first few months, only for it to suddenly shift into much lighter, more interrupted sleep. So before we get into numbers and charts, it’s important to say this: sleep recommendations are helpful, but they are not a strict rule. Every baby is different, and trying to force a baby into a rhythm that doesn’t fit can be exhausting for everyone.
Why Enough Sleep Is Crucial for Your Baby
Sleep plays a much bigger role than just rest. It affects your baby’s development, mood, and ability to settle.
Enough sleep helps your baby:
- Process new impressions and support brain development
- Regulate emotions and reduce fussiness
- Grow physically, as growth hormones are released during sleep
The Impact of Sleep for Safety and Health
When babies don’t get enough sleep, it often shows up as short naps, difficulty settling, or increased crying. At the same time, sleeping “too much” isn’t usually something to worry about in the early months, as long as your baby is feeding well and developing normally.
This is where many parents feel unsure. Is my baby sleeping too little? Too much? The truth is that both can happen, and both can shift quickly.
Key Takeaways
Before diving into the details, here are a few important things to keep in mind:
- Baby sleep needs vary more than most parents expect
- Sleep patterns change constantly, especially in the first months
- More sleep is not always better, and less sleep is not always a problem
- Your baby’s rhythm is often a better guide than strict schedules
Baby Sleep Chart: Recommended Hours From 6 Weeks to 6 Months
Sleep charts can be helpful, especially when you’re trying to understand what’s typical at different stages. But they should be used as a guide, not a goal.
How much sleep should a 6 week old baby get?
At around 6 weeks, babies typically sleep between 14 and 17 hours over 24 hours. This sleep is usually spread out in short stretches, both day and night. This stage often feels unpredictable. You might feel like your baby sleeps all the time, or barely at all, and both can be normal.
How much sleep should a 3 month old baby get?
Around 3 months, many babies start to develop slightly longer stretches of sleep, often totaling 14 to 16 hours per day. This is also when some parents start to notice patterns emerging. But just as often, those patterns change again. With my third, this was exactly when sleep went from “too much” to suddenly feeling like far too little.
How much sleep should a 6 month old baby get?
At 6 months, many babies sleep around 12 to 15 hours per day, with longer nighttime stretches and 2 to 3 naps during the day. Some babies begin to settle into more predictable rhythms, but many still wake frequently. Both are completely normal.
Quality Over Quantity: Understanding Light vs. Deep Sleep
It’s not just about how long your baby sleeps, but how they sleep. Babies spend a lot of time in what’s called active sleep, which is lighter and more restless. This is why they move, twitch, and make sounds while sleeping. Deep sleep, or quiet sleep, is when their body is more still and restorative processes happen.
Many parents worry when their baby seems noisy or unsettled in sleep. I did too with my first two. I often thought they were awake and picked them up, only to realize later that I had probably woken them myself. With my third, I handled this differently. I gave her a little more time before intervening, and often she would settle on her own as she moved between sleep cycles. If you’ve ever wondered why your baby cries or makes sounds in their sleep, it’s often because they are transitioning between these cycles, not because they are fully awake.

Can a Baby Get Too Much or Too Little Sleep?
This is a question many parents ask.
Can a baby get too much sleep?
In the early weeks, it’s usually not a concern if your baby sleeps a lot, as long as they are feeding regularly and gaining weight. Some babies naturally sleep more than others.
What happens with too little sleep?
Too little sleep often shows up more clearly. Babies may become overtired, which can make it harder for them to fall asleep and stay asleep. This is where many parents feel stuck. The more tired the baby gets, the harder it becomes to help them settle.
Sleep Readiness: Helping Your Baby Fall Asleep
Instead of focusing only on the clock, it can be more helpful to look at your baby’s cues. Some common signs that your baby is ready for sleep include:
- Slower movements or less engagement
- Looking away or losing interest in surroundings
- Fussiness that builds gradually
In the early months, I followed my babies’ rhythm almost completely. Over time, I tried to introduce more structure, but I also learned that routines are not fixed. They change as your baby grows. Even now, with my youngest at 19 months, sleep is still evolving. She wakes early, often between 4 and 5, and still needs a short nap before daycare. But from experience with my older children, I know that these phases do pass. For many families, closeness and movement play a big role in helping babies settle. Whether it’s holding, rocking, or gentle motion in a stroller, these are not bad habits, but ways to support your baby’s natural need for comfort.
When Sleep Feels Extra Challenging
Sometimes sleep struggles have underlying causes. If your baby is very unsettled, it can be worth considering:
- Feeding issues, such as tongue-tie
- Sensitivities, like reactions to milk protein
- Formula type, as some babies tolerate goat milk-based formulas better than cow’s milk
If your baby cries intensely for long periods, especially in the evenings, it could be colic. While I didn’t experience this myself, many parents find that movement can help soothe these periods. Also, having a baby with colic is extremely hard. Don't be scared to admit you need help. I will do god for you both.

Summary: Meeting Your Baby’s Ideal Sleep Needs
There is no perfect number of hours that works for every baby. Sleep charts can guide you, but your baby’s behavior, cues, and overall well-being are just as important. Trying to force a strict routine too early can sometimes create more stress than it solves. In the beginning, following your baby’s rhythm can be the easiest path. Over time, routines can develop naturally, but they will continue to change. And even when it feels like nothing is working, it’s worth remembering that sleep evolves. What feels difficult now often looks very different a few months down the line. If you’re looking for gentle ways to support your baby’s sleep, tools like consistent motion can make those transitions between sleep cycles easier.
Frequently Asked Questions
Should babies have more light sleep or deep sleep?
Babies naturally spend more time in light (active) sleep than deep sleep. This is a normal and important part of their development.
Why do babies cry while in deep sleep?
What looks like crying is often part of transitioning between sleep cycles. Babies can make sounds, move, and briefly fuss without being fully awake.
What does a colic cry sound like?
Colic crying is often intense, high-pitched, and difficult to soothe. It can last for long periods, especially in the evening.
Do colic babies cry all day or just at night?
Many babies with colic cry more in the late afternoon and evening, but it can happen at different times depending on the baby.
