Welcoming a newborn into the world is both magical and exhausting. You might find yourself staring at your baby, wondering if it’s normal that they seem to be sleeping… all the time. If you’re googling “newborn sleeping too much,” you’re not alone—and the good news is, in most cases, it’s completely normal.
In this article, we’ll walk you through what’s typical, what’s not, and when it might be time to check in with your pediatrician.
How Much Sleep Do Newborns Need?
Newborns sleep a lot. Like, a lot. On average, babies under 3 months old sleep between 14 and 17 hours a day, and some may sleep up to 18 or 19 hours. But they don’t do it all at once—most sleep in short stretches of 2–4 hours, waking for feeding, diaper changes, or just a cuddle.
This constant need for sleep is part of your baby’s development. Their brain and body are growing rapidly, and sleep helps support everything from brain development to immune function.
So yes, it’s completely normal for a newborn to snooze much of the day (and night).
When Is Too Much Sleep a Concern?
While long stretches of sleep can feel like a blessing (especially after a tough night), there are a few signs that your baby might be sleeping too much.
Here’s when to pay closer attention:
- Your newborn consistently sleeps more than 4–5 hours between feeds in the first few weeks
- They’re hard to wake up or seem unusually lethargic
- They’re not feeding well or show signs of dehydration (fewer wet diapers, dry lips)
- Your baby isn’t gaining weight at a healthy pace
- Their wake periods are very short or non-responsive
If you notice any of these signs, check in with your pediatrician. Often, it’s nothing to worry about—but it’s always worth getting professional guidance.

What Can Cause a Newborn to Sleep More Than Usual?
Sometimes, extra sleep is just what your baby needs. But there are a few common reasons your newborn might be sleeping more than average:
- Growth spurts: Babies often sleep more during periods of rapid development.
- Feeding difficulties: Babies who aren’t getting enough milk might sleep more out of exhaustion.
- Jaundice: This common condition can cause babies to be sleepier than usual.
- Infections or illness: Even mild colds or fevers can make a newborn more tired.
If your baby seems extra sleepy and you suspect something’s off, don’t hesitate to reach out to your pediatrician.
When to Call the Pediatrician
You should contact your healthcare provider if:
- Your newborn is hard to wake or seems very drowsy all the time
- They’re not having enough wet diapers (at least 6 per day after day 5)
- Your baby is losing weight or not regaining their birth weight by 2 weeks old
- They’re not latching or feeding well when awake
Remember: you’re not overreacting—your peace of mind and your baby’s well-being are always worth a quick call.
Sleepy Babies Are Usually Healthy Babies
In most cases, a newborn sleeping too much is simply a sign of healthy growth and development. If your baby is feeding well, gaining weight, and has alert moments, you’re likely in the clear.
Still unsure? It never hurts to ask your doctor or a lactation consultant for reassurance. Parenting is a learning curve—and you’re doing great.
