Grant's Got New Tricks

Grant's getting so big and it seems like he learns new things every day. He's saying more actual words finally. He can say "nana" for banana, mama, daddy, uh-oh, "caca" (cracker), and his most recent word "moo" (we're working on animal sounds).
I've been signing with him since he was about 4 months old, and last month he finally caught on to saying "please" and "more" all by himself, without us prompting him. He's been practicing eating with utensils (that's always an adventure).
He's also trying to do some tumbling. I think he gets this from the girls at his babysitter's house. They're about a year and two years older than he is, so he tries to copy what they do.
He's very active and runs everywhere, from room to room and all over outside. He's actually a little more cautious outside since our yard is so uneven, he has to watch his balance a lot.
