I just wanted to add my response. I was concerned about at what ages babies are supposed to start doing certain tasks. I found that my child would do things that said babies 4 months older then her in the "advanced" cartegory would do. I thought wow my baby is advanced! LOL but some of the things kids her age at the "normal" category she hadn't even begun. I think babies grow at their own pace. Wait a little longer and see what happens. Good Luck! 9Oh and my baby started to pull herself up at around 8 months, but didn't crawl till 11 months, and walked at 12 months).
