I agree it is neat! The only other worries I really had with my daughter was doing all the basic stuff like crawling, pulling up to stand, and walking. Our doctor sent us to PT and OT, while the doctors at the follow-up clinic in the NICU told us that she was doing really really well for being born at 29 weeks. I feel like my doctor just doesn't really understand things about preemies, which isnt his fault, and he expects them to do those things when other kids do them or maybe a few weeks later. She didn't crawl until 11 months, pulled up to stand at 13 months, and walked at 17 months and the funny thing is that we took her out of PT and OT before she did any of this! I think alot of the problem was that she was so small size wise and she was scared, you could tell she was scared, about falling, but once she got over that she did really well. How about your son did he have any issues?
