Nightmares in Babies

Although it’s well-known that older children have nightmares, the idea of your tiny baby experiencing one can be heartbreaking. While less common in younger babies, nightmares can still occur.

If your baby wakes up crying at night, a nightmare might be the reason, although it's rare. Keep reading to learn when babies might start having nightmares, why they happen, how to prevent them, and what to do if your baby experiences one.

Can Babies Have Nightmares?

Nightmares and dreams in babies are quite mysterious. Even for adults, dreams can be puzzling!

There’s a debate on whether a younger baby’s brain is developed enough for nightmares. Since nightmares are dreams that wake you up, it’s challenging to determine if your baby is waking due to hunger (which is common in newborns and young babies) or a nightmare. Most kids have their first nightmare around 1.5 to 2 years old, when they can talk about it.

Some experts think young babies might have nightmares because they spend a lot of time in REM sleep, the stage where dreaming happens. But it's not certain.

Newborns and young babies often wake up crying at night, usually because they’re hungry. Since they can’t tell us, it’s tough to know if a nightmare is waking them.

Why Do Babies Have Nightmares?

Nightmares are dreams that wake you up and are a normal part of growing up. Your baby's developing imagination can lead to both pleasant dreams and nightmares.

According to the National Sleep Foundation, nightmares are very common, affecting about half of kids aged 3 to 6. Babies might have nightmares for various reasons, and different situations can make them more frequent.

If your baby is sick, stressed, or sleeping in a new place, they might have more nightmares. If nightmares seem frequent, talk to your pediatrician.

When Do Babies Start Having Nightmares?

Babies often have their first nightmare between 1.5 and 2 years old. However, some might start as early as 6 months. Nightmares typically peak between ages 3 and 5.

It’s uncertain if a newborn’s brain is mature enough for nightmares.

What Do Babies Have Nightmares About?

There’s no way to know exactly what a baby has nightmares about, or even if they have them.

For older kids, nightmares are often related to something that happened during the day, a book they read, or a show they watched. The same goes for good dreams.

What to Do if Your Baby Has a Nightmare

If your baby wakes up from a nightmare, they’ll likely be upset and call for you. Comfort them with cuddles and reassurance to help them relax and go back to sleep.

For a child who can describe their nightmare, let them share it with you. Explain that nightmares aren’t real and just bad dreams to help them feel safe and ready to sleep again.

How to Prevent Nightmares in Babies

Everyone will experience bad dreams, but there are ways to reduce or prevent nightmares in babies:

  • Stick to a consistent bedtime routine for safety and security.

  • Read happy stories and avoid scary shows before bed.

  • Explain that any nightmare they had was just a dream, not real.

  • Remind your baby that you’re close by and they’re safe.

  • Put your baby to sleep according to their wake windows to align with their natural rhythm and prevent overtiredness or stress before bed.

FAQS AT A GLANCE

Nightmares are bad dreams that cause your baby to wake up upset. They occur during the REM sleep cycle, which happens later in the night. You can often recall what happened during a nightmare.

Conclusion

No one wants their baby to have a nightmare, but it’s a normal part of growing up. While there’s no surefire way to prevent them, there are ways to reduce the risk.

If your baby seems to have frequent nightmares or you’re unsure if they are having one, talk to your pediatrician for personalized advice.
