my   6 week baby shakes one leg sumtime ... is it normal ????

it's baby used to do that

yes normal..legs hands too...

its most likely to be fine as babies do have involuntarily move body parts but if its a very repetitive action pls consult the doc. Not to scare you, but sometimes in rare cases it can be a neuro issue.

its absolutely normal. nothing to worry

if this does not rectify by 8 mts pls consult a doctor. as of now its absoutly normal. happens due to nerve sensations travelling to the brain. nothing to be scared of.
