My DD is nearly 11 months old. She isn't crawling, she rolls to get about. She doesn't initiate pulling herself up or try to sit up from lying down, though if sat up she is sturdy. Recently she has become much less likely to respond to her name and has started what I can only liken to baby tai chi, with her hands/arms. She seems fascinated with her hands. She does babble but mainly gagaga; whereas recenly she'd been saying dada. She sleeps and eats well. I've requested my HV come and do her 1 year review, which is organised for mid November. I'm really worried about her development and would welcome your though.
