I never thought this would be something I'd be worried about, but here I am. Worried FTM. My 9mo is very confident with people he doesn't know. For example, at baby group, he will crawl up to other mum's and get them to help him stand up by holding hands etc. at first I thought it was really sweet and he was just sociable. But I thought babies were meant to be cautious of strangers and now I'm worried? He's so happy at baby group that I feel silly for worrying but it also makes me worry about his safety etc with strangers.
