I will say, my daughter turned 8 months old today. She sits up really well but enjoys throwing herself backwards in protest when shes had enough, so I keep a cushion behind her. She isn't crawling yet. But she will roll around and pull herself along using the rug. Despite my best efforts in trying to get her to crawl, she just isn't ready yet. She will happily stand up with you holding her hands all day long though. But she is a diva, so dramatic, she babbles, blows raspberrys, grabs, bounces, has the most intense stare and LOVES people watching. I get a bit twitchy when I see people say ronnieblesshim should be crawling by now or standing, that isn't really the case. Every baby is different and by the time they turn 5 and are in a classroom of kids you won't be able to tell who crawled at 5 months or who crawled at 9 months. But I digress.....
My point is, she doesnt crawl yet or pull herself up, and i feel she shares that similarity with Ronnieblesshim, but he just seems disinterested in everything. We've never seen him rolling about over the floor. He just sits there blankly looking at his toys. The odd smile here and there.
Sorry..that was a bit lengthy. I don't mean any offence by anything I've said.
