Q: Your Baby's Sleep Sounds: When to Worry and When to Relax

Is it normal for a baby to make strange noises while sleeping?

Hello, Doctor: I would like to ask you a question.
My baby is almost 2 months old (will be 2 months on the 15th).
When my baby was about 2 weeks old, I noticed that she makes a certain sound while sleeping, and I have recorded it.
Could you please check it out on my blog? Thank you!! http://www.wretch.cc/album/album.php?id=lovebaby0813&book=1 This sound only occurs during sleep; sometimes it happens, sometimes it doesn’t.
Changing her position sometimes stops the sound, but other times it continues throughout the night (sometimes it occurs while she is drinking milk as well).
However, she sleeps soundly and her eating and bowel movements are normal, so I’m not sure if this sound is normal.
Will it go away on its own? Additionally, I would like to ask if my baby should be evaluated by a doctor since she doesn’t smile yet when I play with her.
Thank you for your response, Doctor!

Hello: When your baby is about two months old, it's normal for them to smile when you play with them, and the timing may vary, so there's no need to rush to have a doctor evaluate it.
I recommend that during the vaccination visits, you have the doctor conduct a health check, especially focusing on growth and development.
For a simple self-assessment, you can refer to the child health handbook.
As for the sounds your baby makes while sleeping, based on your description, it seems to stop when they change positions.
This could be due to mucus sounds, or a small amount of milk remaining in the throat, or regurgitation causing swelling in the nasopharynx or larynx.
It's important to ensure proper burping and to avoid regurgitation.
I hope my response is helpful to you.
Thank you for your message!

More Info

When it comes to understanding your baby's sleep sounds, it's essential to differentiate between normal behaviors and those that may warrant concern. Babies, especially in their early months, often make various noises while sleeping, and many of these sounds are entirely normal.

Common Sleep Sounds in Infants
1. Grunting and Gurgling: Many infants produce grunting or gurgling sounds as they transition between sleep cycles. This can be due to their immature respiratory systems and is often more pronounced during REM sleep when they are dreaming. These sounds can also occur when they are adjusting their position or if they are experiencing mild discomfort, such as gas.

2. Crying or Whimpering: It's not uncommon for babies to whimper or cry softly in their sleep. This can be a part of their sleep cycle and may not indicate that they are fully awake or in distress.
3. Snoring or Nasal Congestion Sounds: If your baby sounds congested or snores, it could be due to nasal passages being slightly blocked, which is common in infants. This can happen if they have a cold or allergies, but it can also occur without any underlying issue.

When to Worry
While many sleep sounds are normal, there are specific signs that may indicate a need for further evaluation:
1. Persistent or Severe Sounds: If the sounds are loud, persistent, or accompanied by signs of distress (such as difficulty breathing, turning blue, or excessive fussiness), it may be worth consulting a pediatrician.

2. Changes in Feeding or Behavior: If your baby is not feeding well, seems lethargic, or has a significant change in behavior, these could be signs of an underlying issue that needs to be addressed.

3. Lack of Developmental Milestones: You mentioned that your baby is not yet smiling. While it's common for babies to start smiling around 6 to 8 weeks, some may take a bit longer. However, if your baby is not showing any social engagement or responding to stimuli by 3 months, it may be advisable to consult a pediatrician for a developmental assessment.

Recommendations
- Monitor the Sounds: Keep a log of when the sounds occur and any accompanying behaviors. This information can be helpful for your pediatrician if you decide to seek further advice.

- Positioning: If changing your baby's position seems to alleviate the sounds, it may be beneficial to continue doing so. Ensure that your baby is always placed on their back to sleep, as this is the safest position.

- Consult a Pediatrician: If you have ongoing concerns about your baby's sleep sounds or development, don't hesitate to reach out to your pediatrician. They can provide reassurance and guidance tailored to your baby's specific situation.

Conclusion
In summary, many sleep sounds in infants are normal and part of their development. However, being attentive to your baby's overall behavior and development is crucial. If you have any concerns, especially regarding their ability to engage socially or any unusual sounds during sleep, consulting a healthcare professional is always a wise choice. Your pediatrician can help you navigate these early months and ensure your baby is healthy and thriving.
