Diego figured out how to get himself into a seated position. He's been trying so hard to do it and I guess last night, he did it while I was in the other room. Jay was with him and didn't see him do it. But he saw that he wasn't sitting and then he was all of a sudden. Jay suspected that he used the activity mat's arches to help himself get there because of the way he was hugging them.
Well, today I saw him do it. And now he does it over and over again. So cool!
