For a child who is behind on gross-motor development, I have one thing to say about Blanket: "the day he does something is the day before he is good at it." This kid takes his time. Blanket is ready learn something new only after he has studied others doing it, and explored his abilities, assured himself he can do it without falling, built up his confidence, and then psyched himself up for it. Then he spends all afternoon mastering it. This is what he did on Valentine's day. Just for fun. He learned to go upstairs by himself.
This doesn't freak me out. I taught him to go downstairs when he was 10 months old so that when he finally learned to go up, he wouldn't fall down. Now he loves to go up and down stairs. He actually went down the other day while I was in the shower. Apparently, the bathroom isn't as fun as it used to be, and he wanted to go play toys with his brother.
In other news, he crawls. For real. He actually crawls. Not all the time, and not always with perfect form, but he crawls. Next comes walking; make that running.
