Mom’s Question:

My baby slept when I was feeding her, and suddenly she started shaking completely. I made her wake up and she was normal.

I am scared; what could this be? Is she having some problem? She is already showing irritability for the past few days. Please help me.



Baby Shaking While Feeding and Sleeping

Have you ever experienced that when you have just fallen asleep, you dream that you are falling? Then you wake up with a jump. That may very well have been what happened to your baby. Some babies also have a slightly immature nervous system, which may cause shaking.

Sometimes shaking in babies can be a warning sign of some neuro problems, but then often the shaking is combined with other indications that something is wrong, like falling behind developmental milestones, for example.

You can read about some warning signs when a baby is shaking here.

However, since you are worried and if it happens again, maybe you should take your baby to see a doctor.

I hope this helps,

Jan 03, 2012 Suddenly shakesby: Del

Periodically when my daughter awakes from her nap, she shakes for about 10 to 20 seconds. It’s as if her nervous system is engaged during that time.

I am not sure what causes it or even what to do about it.

Mar 12, 2012 acid refluxby: Anonymous

our son had something similar to what you are describing at the end of feedings…his arm would twitch like a muscle spasm. we were very worried and even went to a neurologist. turns out it was something called sandifor’s syndrome, which is basically a kind of acid reflux that he grew out of. I think the doctor prescribed previcid or something which helped, but eventually, it went away all together.

Sep 06, 2012 Same issue!by: Anonymous

I just had the exact same thing happen- same-age baby, too. She was feeding and getting sleepy and then she just started shaking. She was still making eye contact and didn’t look upset, but it scared me half to death. She seems OK now, just nursing and getting sleepy. Original poster- did you ever get an answer to what it was?

when I went to dr they asked me to have a neuro test, and they wanted to give anesthesia to 4-month-old baby which i was not interested in.

I concerned other doctor and they said sometimes kids may be dreaming about something and they start doing same action as they are doing in their dreams.

shaking part continued for almost a month but then it was all normal so i never visited the doctor who prescribed to go for neuro test

i will suggest please go to doctor once coz most of the times doctors saying bring peace to our mind

Oct 26, 2012 Similar Situationby: Lisa

I woke my 4-month-old up for feeding today, and she started shaking after being up for about 10 – 15 min and making lots of groaning noises! She is still shaking at the moment, she ate fine? Just wondering if anyone else has seen this, I am contacting my dr. tomorrow morning!

Nov 20, 2012 baby shakingby: Alma

My baby was 4 months when it started to happen. I was nursing him, he’s almost asleep, then he would shake his whole body. I was so terrified. I woke him up and the shaking stopped. It lasted maybe 4 seconds. The third time it happened, I called the doctor because I was thinking it was seizure. He said seizure last for minutes and you cannot stop it. So definitely my son’s shaking was not seizure. He said babies also twitch like adults when they are asleep. With babies, their muscles are not well developed yet so if one muscle jerks, the next muscles will jerk too making the baby shake. He said it’s nothing to worry about.

Feb 16, 2013 nothing to worry aboutby: Rita

I just got back from my daughters ped and she was doing the same thing…I would be feeding her and she would start to fall asleep and she would start shaking, I was told that sometimes babies do this he told me some big long word that i can not remember right now sleep something but it is nothing to worry about and was not a seziure as i was afraid it was as they run in the family rest assured that this is normal in some babies!

I’m the one who posted back in Sept- for the record this happened many more times, but it was nothing. I’ve got a very happy, very healthy 14 month old now, and I haven’t seen this issue in months. I took her to the doc when it happened and was told that it was just the result of an immature nervous system and that it was nothing at all to worry about. Always nice to hear it from the doc, though :)

What’d I’d say is this- you are the best judge of what’s up with your baby. It’s SO normal to be concerned, it’s our lot in life as parents! However, trust your instincts and take them in if you’re worried. Always better safe than sorry, but thankfully it sounds like what we all experienced was a pretty normal, harmless thing.
