He's just turned 10 months yesterday. He's not pulling to stand, he can't weight bear, he can only stand holding onto something for a few seconds, he doesn't wave clap or point but he bangs 2 toys together, he rarely babbles eg mamamama dadadada bababaa, he's not crawling he's trying but he just physically can't and he gets frustrated. He can't pick up finger food from a plate and feed himself. He hates loud noises and people raising their voice and he takes these wee episodes where he would stare blank into space. He only started rolling over at 9 months. Am I worrying too much?!
