Hi T.,
My daughter just turned 9 months old yesterday, and I have had the same exact questions and concerns for her. Like your daughter (while on her stomach) she ends up pushing herself and sliding back on her tummy, and rolls EVERYwhere. She even flips while trying to change her diaper. She just recently, since last week, has been getting on her hands and knees, but has yet to actually coordinate her limbs to start crawling. She is standing w/ assistance only, but has had very strong legs since she was a newborn. She can not pull herself up to standing either. Incidentally, we just had her 9 month check up this morning, and her pediatrician said that she should be doing these couple of things (crawling, pulling to stand) in the next month or so and to not worry (as of course these are all just general milestones that the 'average' baby reaches). Is your daughter babbling, imitating sounds and playing fun games like peekaboo or pattycake? Apparently these are other 'characteristics' of babies of our's age. Our baby is also still on 2nd foods, because I'm still so paranoid about choking. Although her doctor said she can start doing finger foods, I do insist on still spoon feeding her (since I still have so much left), but will give her a low sodium Ritz cracker while supervised every once in a while b/c she seems desperate to try all adult table food. Doc also mentioned soft food like banana, mashed veggies, etc. although we haven't experimented too much with these yet.
