Why Do Babies Laugh In Their Sleep And What Does It Mean

Many parents spend hours awake next to their babies when they are asleep. Occasionally, they will find the baby laughing during the sleep process and while this is quite a common occurrence, many people might be wondering what it means. Some parents also scramble, wondering if it might be a neurological issue.

However, chances for it to be a neurological issue are quite rare and most times it is simply a common occurrence found in babies. In this article, we have looked a little deeper at some of the reasons babies might laugh in their sleep and this should give you some peace of mind when this does happen to your newborn baby.

Reasons You Baby Might Be Laughing While The Sleep:

  1. Active sleep:

One of the reasons your baby might be laughing will all come down to active sleep. When the baby completes a REM cycle, they might still be active in their minds. During this phase, the baby might be dreaming and this could be one of the major reasons the baby is laughing. However, the baby should not have any recollection of this.

This phenomenon also happens to adults and they occasionally laugh and even talk during their sleep cycles. Most people will wake up the next day with absolutely no recollection of what happened in the dream.

  1. Involuntary movements:

Often times, the baby might have twitches and things in their face. This could also give the impression of the baby smiling or even laughing. However, this is mostly attributed to the nervous system and the baby will not actually be laughing or even be conscious if they are in a very deep sleep as part of the REM cycle.

This is another phenomenon that seems to happen to adults as well. Twitches can be a problem with the nerves or even small muscle contractions in the face. Should this be a serious thing, the baby will potentially wake up and start crying. Most people have experience face cramps.

  1. Seizures:

Small seizures that could last between 10 and 20 seconds have also been seen in babies. However, this is on very rare occasions and while it might not mean much, it could lead to bigger problems. If your baby is suffering from small seizures, it will be a common occurrence and you might even find them giggling uncontrollably when they sleep.

Research has shown that these small seizures generally occur, as the baby is falling asleep or when they are waking up. It starts around the 10-month mark and many babies will also grow out of it. Before you go into a massive state of panic, we would once again like to remind you that this only happens on rare occasions and you do not need to keep a constant eye on your baby.

If you notice this often and it happens during the day when the baby is awake, you should talk to your pediatrician. They will have much more knowledge and experience when it comes do diagnosing problematic situations and to ensure that your baby does not suffer from any of them. Your pediatrician will be your best friend, as your baby grows older.

Should You Worry If This Happens?

As we have already mentioned, most new parents might worry and start assuming things that aren’t real. However, the baby will be fine and you should not take it too personally. Babies do go through phases that help them grow and they also learn to adjust to noise and everything surrounding them. Often times, the reaction will be temporary to adjust.

If you do find yourself worrying or if the symptoms persist, it will be better for you to consult your pediatrician and it is important to make sure that the baby is still doing well. Once the baby is diagnosed, you will know exactly what you are dealing with and the doctor should advise you on how to proceed. Nevertheless, we believe that the chances are it is not serious and your baby will be doing perfectly.


Babies are amazing and they have amazing reactions to their surroundings and life in general. Sometimes they may leave us in awe or even biting our nails, but most of the time, it will be a false alarm. When it comes to caring for your baby, your pediatrician will be your best friend and whenever you find yourself in doubt, it is really important to consult them.
