DS has been on the quicker developer - army crawling & pulling self up by 6 mo and crawling just short of 7 mo. DH was an early developer (walking BY 8 months, etc.). It appeared DS was on a similar path, but now I feel like he's stalled out. By no means do I want to rush him, he'll do things on his own time, and frankly, I'm ok with him just crawling right now.
He will be 9 months next week & has made NO effort to walk. he occasionally cruises the furniture, but finds it easier to sit down & crawl to what he wants & then pull himself up. He can pull himself up on anything with one hand, and barely even really uses it for support. However, he makes no attempt to stand by himself, and when you try to hold his hands & have him walk between your legs, he sits down. It used to take him a few weeks to master a skill & then he was quickly onto learning the next.
I noticed this slow in development around the time we switched him from a daycare center where he was with kids his own age, but only wanted to watch & play w/ the older more developed kids, to an in home daycare where the only other kid is a 4 year old (he plays with her a lot). Is it a coincidence? Is this normal for them to slow down?
