My son has been doing the same, I’ve assumed it’s when he doesn’t want the bottle because he won’t open his mouth for it either
My little boy has been doing this for a while when having his bottle. It seems to me like he is going into a milk trance. He isn’t doing it as much anymore (he will be 26 weeks this week) but it still happens the odd time
Hold his arm firmly when he next does it. If it stops then it’s just normal movement. If it still jerks despite firm pressure it is involuntary and you could always go see doctor. That’s the advice we’ve been given to test for involuntary spasms as our little girl has epilepsy
My little one does it too quite a lot when having his bottle. Xx
Thanks everyone xxx
Yep also very loudly banging all toys on the high chair tray. They are just discovering their limbs 😄
My little boy always does this and has for a while now x
