B will be 11 months old on Monday and still isn't traditional crawling or sitting himself up. He army crawls everywhere and pulls up to standing from his belly. I feel like he isn't sitting himself up because he never crawled on all fours. I'm so nervous that at his one year check up next month his pediatrician is going to tell me he's behind.
My other concern is his weight. At 6 months he was 16.5lbs and at 9 months he was only 18.3lbs. Now at 11 months he's only just over 19lbs so he's only gained about a pound in 2 months. He's stayed consistently in the 95th % for height but his weight percentile keeps dropping. He eats a ton and has plenty of wet and poopy diapers but still doesn't gain nearly as quickly as he was. The ped isn't really concerned because my husband and I are both thin and DS is very active but I still can't help but feel like I'm doing something wrong because he isn't gaining as much as he was.

Regarding weight, the rate of gain drops way off around your LOs age...and there is often a notable drop off once they really get mobile (burning more cals). He is a healthy weight for a one year old, you're doing good momma.
Regarding the sitting...he CAN sit, just not get himself into the position, right? I dont think I was ever asked about that at an appt. My ds didnt get himself into a sit until he was crawling on all fours. I think he was about your ds age when he figured it out.

Thank you hun. Its hard not to worry. If we put him in a sitting position he can sit that way for long periods, reach for stuff, play etc. He just hasn't figured out how to get into a sitting position on his own yet and I think a lot of it is because he has never crawled on all fours.

My boobies belong to cour10e
She was also only 17 lbs. when she was weighed about a month ago, but she seems happy, can devour whole meatballs, and has a chubby little belly.
So in other words, I wouldn't worry! It sounds like he's got his own thing going on.
