B is learning that he has influence on his surroundings, the world isn’t just something that has to happen to him.
It started maybe a month or so ago when I was gently leaning him back to put him in his sleep sack. He suddenly threw his hand out and caught himself, preventing me from lying him down. Actually, even a bit before that he started pushing away his bottle when he didn’t want any more.
Now he’s grabbing at the pages in his board books, trying to turn them.
It’s pretty fun to watch.
