3-Month-Old Sleeping A Lot: Should You Be Concerned?

Babies sleep a lot. This is common sense for any new parent, particularly if you’ve had a baby for a few months. In the newborn stage, they can sleep up to 17 hours a day! They’re like a cat, minus the fur and the purring. 

However, your baby will sleep less with time, and by three months, your baby should be sleeping less. However, if they’re sleeping more, you may wonder the exact reason why. We’re here to help you find the answer. Is it normal to see your baby sleeping more than usual? Let’s find out.

How Much Sleep Does A Baby Need? 

First, you should see whether or not your baby is actually sleeping more than usual. You have to remember that with babies, they can sleep a lot and don’t have a consistent sleep schedule due to their lack of circadian rhythms, or biological clocks. They can’t tell the difference between day and night, and this can cause the baby to wake up during random parts of the night. 

A newborn typically sleeps around 8 hours at night, and naps for around the same amount of time. They may sleep a total of about 15 and a half hours, though some newborns may sleep for even longer. 

A three-month-old sleeps for 10 hours at night and may nap for about five hours. So at three, the amount of time they sleep isn’t too different than a newborn. 

A baby at six months will sleep a bit less. They’ll sleep more at night, and nap a little less, and get around 14 hours of sleep a day. 

Nine months is about the same as six, with slightly less nap time. 

Finally, at 12 months, your baby will sleep even less in their naps, and get around 13.75 hours of sleep. 

But we can’t stress enough that it varies from baby to baby, so if they’re sleeping a bit more than what is described here, that’s nothing to be worried about.

Why Your Baby May Be Sleeping More 

There are quite a few reasons why your baby may sleep more, including: 

A Growth Spurt 

Babies are growing quite a lot. Every month, they grow a little bigger and gain more independence. During the first few years, that’s when the growth is the most rapid, and because of all the growth, your baby needs the energy to compensate for that. That’s where the sleeping comes in. A baby will sleep quite a bit to help them grow, and the amount of sleep they need may be connected to them sleeping so much. 

When do growth spurts happen? It all depends. Usually, a baby notices a major growth spurt in four months, but some babies may have it earlier, so a three month old sleeping because of a growth spurt isn’t uncommon. 

If you want to make sure the baby is sleeping due to a growth spurt, another way you can figure out if it’s one is if your baby is eating more. In addition to sleeping more, your baby will eat more as well. Your baby needs all the energy they can get, so offer an extra bottle or a breast.


You typically don’t see teeth in a baby until around 6 months, so you may think that you can rule teething out. However, teething involves the teeth moving around in the gums, and this phenomenon can happen as young as two months, so it’s possible. Whenever a baby is teething, it’s painful and keeps them up at night. When they wake up at night and sleep less due to teething, they’ll end up sleeping more once that teething session is over, which is why you may see your baby sleeping more than usual at three months. 

Another reason teething makes a baby sleep more is that a teething session can give your baby a fever, which can make your baby sleep it off, which is always a good thing for them. If your baby is sleep, they need all the rest they can get, so give them cuddles and love, and let them sleep in a nice, darkroom.

They’re Just Like That 

Every baby is different, and they sleep differently. Eventually, babies will all have similar sleeping times, but at this young of an age, a baby does not have a sleep schedule. Instead, they sleep whenever they want and will wake whenever too. 

A three-month-old sleeping too much is usually no cause for concern. In most cases, the baby is just getting their Z’s in, and as a busy parent, you may feel glad to have a baby that sleeps so much. 

Don’t Be Afraid To See A Doctor

With that said, if you’re a little worried about your baby sleeping too much, and you think it may be something more than what is listed, there isn’t any shame in seeing your baby’s doctor to rule out another disease. Sleep apnea can happen in babies, and other sleep disorders happen as well. 

Granted, a baby sleeping too much is rarely a cause for alarm, so don’t go to the doctor the first time you see your baby sleeping too much. Remember that this is quite common. 

In the meanwhile, keep your baby entertained while they are awake. Give them toys, affection, and talk to them before your baby falls back asleep.

When a baby is sleeping a lot, you should probably let them do that. Babies need lots of sleep to grow, and unless their sleep patterns are way beyond the average, it’s no cause for alarm. In fact, if your baby sleeps a lot, sleep as well. You will need that sleep for when they hit the toddler stage, where the sleeping is a little less and they’re forming somewhat of a sleep schedule, yet other sleeping problems like sleep regression can occur as well. Here’s hoping your baby is having some rad dreams.
