Charlie really is making visible improvements. The thing is, they aren’t really photo-worthy OR they are difficult for predict. For example, yesterday morning I distinctly heard him say “me me.” This is great because he doesn’t make the m sound very often, but it’s not something you can snap a picture of.
Here’s a picture of the cute curls he’s been getting on the back on his head. Here he’s just holding himself up so he can see better as we take a walk around the neighborhood.
Finally, here’s a picture of his commando-crawling behavior. I don’t know if it’s clear, but he’s definitely strong enough to do it–you just need to help him by touching different parts of his body. Often I have to help out with the right hand. I would say that his motor planning is a bigger deficit than his strength. He knows what he wants to do–he just can’t get all the steps straight.
