Really concerned ...

Kv

I have noticed about a week ago this but today I noticed it even more which is freaking me out and I just can’t wait until I see my daughter’s pediatrician to ask her about it also. But when I’m feeding my baby as soon as she starts shewing she makes this jerking head and left arm movement.. it’s king of like she’s throwing herself back on the chair and swings her left arm... she’s fine chewing the food and everything she doesn’t seem in pain or anything it’s just the way she makes that head and arm movement that really concerns me. Has anyone else noticed anything similar with their babies ?!
