Just some thoughts and videos of Ben
So, I (or I think I can more aptly say "we") are a little bit concerned about Mr. Ben. He is getting darn close to 11 months old (!!!!!), his adjusted age is 8 months and 1 week. It is hard to know if our expectations are too high, or if we are being overly sensitive about these things. I am posting these videos to maybe get some more feedback from other moms who have been through this.
The first video is of him army crawling. He started doing this about a month ago, shortly after he got up on his hands and knees for the first time. He can move pretty quickly and can go about anywhere he wants too, even now he can go on slippery floors without a problem. My main concern here is he seems to be using his right arm to power through and propel himself, his left arm is kind of just there and moving a little bit but doesn't appear to be providing much assistance.
When he gets up on hands and knees he uses his left arm to try to grab things while his right arm supports his weight. I don't believe that he is able to support himself with his left arm; when he tries to lift his right arm off the ground his left arm immediately folds and he ends up on the ground.
I'm going to try to post a second video of him "sitting". He can still only sit for a few seconds at a time. He falls right over with almost no reflex (that I can see) of trying to catch himself with his arms. I propped him up and immediately let go of him; the entire video is 8 seconds so that shows you how long he is sitting. Every once in a while he will sit for longer, sometimes I'm not sure if he just doesn't WANT to sit, or if he CAN'T sit, know what I mean? He is a baby on the move and he likes to go, go, go so perhaps sitting just isn't motivating for him.
This last video, if this works, is of him in the crawling position. You can see his left hand kind of in a claw/loose fist, which again is pretty typical. He CAN open it; it's just that when he does this it is normally not open. Again, not sure if this is something to be concerned about or not.
