Isaiah knows "more" and he mut have learned it from daycare because I had no clue what it was. I thought he was just spazzing or had some sort of weird tic or something every time he would say "more" (and sign with it). Then my SIL was like "does he know sign language?" Whoops.
Isaiah says "all done" for everything too: "all done car seat," "all done stroller," "all done diaper change," etc., whenever he is trying to get out of something or doesn't want to do it/be there anymore.
