Kaz - I would not be worried at all!! The stupid MHCN wanted to send us to an audiologist for Juliette's hearing because she wasn't babbling properly at 8 months. She started the next day and babbles constantly now!

DD1 didn't crawl until she was over 9 months and she was only rolling one way too. I was chatting to a friend who said her daughter just started to crawl last week at 11 months. Crawling is not even a milestone as not all babies crawl - some bottom shuffle and some just get up and walk.
