I am finding this 9 month old kind of behind in most physical areas. He is sitting up, but not very steadily (he is easily knocked over). He does not lift his arms to be picked up, but is rather limp when I pick him up (and heavy!). He can roll over, but other than that is not very active (not much kicking or waving arms etc). He has not mastered the pincer grasp either, which is part of the problem with the finger foods. He sleeps a lot, which may be why he isn't as good at these things, but I am suspecting that his parents may use exersaucers, bumbos, etc a lot as he seems quite comfortable when I put him one. I try to give him as much time as possible on the floor to strengthen his muscles, but I only have him 3 days a week. I did put some puffs in his mouth, but he still didn't get how he should pick them up. I think I will try taking his hand and teaching him to pick them up and see if that helps. He can eat mum mums, which is the only other thing his parents have given him. They think that since he has no teeth, he cannot eat finger foods. I told them they can gum things, but I don't think they were convinced. I guess it may be slow progress.
