Hi, my DD is 10.5mths and I'm a bit worried about her development. She seems slower than her older brothers to do things but not very slow if that makes sense. She is crawling but not yet cruising. She babbles but not with the vigour that the boys had. they also had 2 or 3 words by now but she seems nowhere near speaking.
However, my main worry is a strange movement she does with one arm. She will raise it up then drop it again. Sometimes 2 or 3 times in succession. It's a fairly quick movement. She doesn't seem bothered by this or even to notice that she's doing it but it's really worrying me. DD does this maybe once every hour or 2 and it is always her right arm. It's not an excited flapping movement as its only ever one side and it doesn't seem to correspond to anything else. She isn't trying to wave or anything.
Just to add that her crawling seems fairly symmetrical but when she first started crawling it was commando style and she would pull herself along using just one arm; the one with the strange movement. she would pull with that arm then reach for toys and stuff with the other arm. She seems to finger feed with both hands and hold toys with both hands. Having said that, her grasp or grip isn't anything like as strong as the boys at the same age but I don't know if that's a boy thing. They walked at 10/11mths if it's relevant. Has anyone else's baby had a similar movement going on? Did they grow out of it?
