Hi there wondering if anyone can shed some light on this!
4 month old really resists me moving her right arm above her head, for example when I need to wash her armpit she resists it being moved up and the same when I need to dry it etc. It can go above her head she'll suddenly relax it and it's fine. I watch her when she's playing and she can move the arm quite freely so it's not like the arm is weak. The other arm goes above her head so freely which is why I'm puzzled this arm just doesn't want to do the same. Will make a GP appointment next week but has anyone had this with their one before?
