my son just turned 5 months yesterday and im a lil conserned that hes not developing like he should. hes just now starting to grab at things and realize that his hands do stuff. he hates being on his tummy and only sometimes remembers that he can actually roll himself back. he hugs his bottle when i feed him but doesnt show any signs of trying to hold it himself and he doesnt eat from a spoon that well at all either. he also is still having trouble with sitting up straight without support. maybe im just paranoid but my 11yr old daughter developed really fast when she was a baby. anyone else have this goin on?
