4 Month Old Baby Arm Shaking

by Issac
(usa)

My wife and I have noticed that our 4 1/2 month old son's arms start to shake when he is attempting to grab something and can't get his grip on or when getting annoyed or sleepy and about to cry. It appears it's mainly when these things are happening around him that this begins.

When we hold his hands, the shaking stops but when you let go, it picks right back up again. The best way to describe it would be as if someone was super excited or nervous that their arms would be shaking in that way. We don't know if this is just a part of growing up or something a bit more serious. These happen throughout the day and other times he holds his hands nice and straight.

Is it any kind of neuro problems??

Would appreciate any input!
Thank you!

Probably normal
by: Baby Help Line - Paula

Hi Isaac and Samisa,

What you describe is probably normal shaking due to your baby's immature nervous system. I remember believing that my first born suffered from some kind of brain damage when he was newborn due to his weird movements and shaking... But it turned out to be completely normal newborn movements.

But remeber that I am not a doctor and hence can not give you medical advice.

Nevertheless, some of the warnings signs to look for when babies shake are the following:

- The shaking occur at any time. If it is is only when changing diapers, feeding, getting angry etc, is is not likely to be for example a seizure.

- The shaking contiues even if you hold the arm.

- Shaking that is bilateral is more likely to be a sign of problems

- The babys is falling behind on developmental milestones

From what you describe, your baby doesn't seem to have these problems. Still, if it was me I would probably take him to a pediatrician anyway, just to be on the safe side and also to get rid of the worry.

I hope and believe that your son is completely healthy. Let me know how things work our for you,

Paula
