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 by reading about the sleep tips below.

How Much Sleep Does A Baby Need? 

First, you should see whether or not your baby is actually sleeping more than usual and not experiencing a normal 4-month sleep regression cycle due or adjusting during sleep training. 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, biological clocks, and waking for night feeds. 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 long after night feedings have ended. Babies who sleep near a white noise machine used during sleep training are likely to sleep for longer periods. 

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

A three-month-old sleeps for about 10 hours at night with sleep training and may nap for about five hours. So at three, the amount of time they sleep isn’t too different than a newborn once they get used to the white noise in your home. 

A baby at six months starts to 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 babies start sleeping even less and get around 13.75 hours of sleep. 

But we can’t stress enough that sleep habits vary 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. Babies have growth spurts during the first few years.  These are the times when the baby’s growth and development is the most rapid. Your baby may sleep longer during a growth spurt because they need to compensate for the extra energy used during this period. When babies start going through a growth phase, they will sleep quite a bit. 

You may notice a change in babies’ sleep schedules when they are experiencing a growth spurt. Many babies will sleep for longer periods during this time and even sleep through the night. 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 3-month-old baby 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.

Teething 

You typically don’t see teeth in a baby until around six 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 is one of the things that often keep babies from sleeping through the night. When they wake up at night and sleepless due to teething, they’ll end up sleeping more once that teething session is over, which is why you may see your baby taking more naps a day or sleeping through the night as early as 3-months-old. 

Teething can disrupt a baby’s sleep schedule and cause the baby to stay awake longer than usual. New parents may notice that the baby’s sleep schedule has been interrupted when daytime sleep turns into hours-long naps. 

Teething can account for 3-4 month sleep regression, and short naps can become hours long sleep sessions. 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 develop their own sleep schedules, but at this young of an age, a baby does not have a set bedtime routine. Instead, they sleep whenever they want and will wake whenever too. 

A three-month-old who falls asleep during the daytime and seemingly 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. Daytime sleep is just as important as nighttime sleep when it comes to sleep training your baby. When you start sleep training to develop your bedtime routine, count the number of naps a day and hours of daytime sleep that baby is getting to learn their sleep routine. 

Don’t Be Afraid To See A Doctor

With that said, if you’re a little worried about your 3-month-old-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 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. Baby’s sleep cycle will eventually stabilize, and hours of daytime sleep will balance with night feedings as the baby falls into a consistent bedtime routine. 

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.
