Last night, we found out / realized / proved that Swe-cha knows his numbers all the way to 100, at the very least. We weren't quite sure before because his school reports only say "Can count from 1-20" and there's a check mark in the column beside it which says he does this well. It doesn't really tell us that he can count beyond that.
These days, whenever he wants to use the "Mommy's iPad" instead of his own, his Dad (Yes, Daddy is the main user of "Mommy's iPad", the name is a misnomer) would say "5 minutes" and they'd start counting 1 to 300.
Last night, Swe-cha counted to 1-100 with minimal coaching. He got stuck at 69, 70, 69, ...
Daddy had to step in and coach him with "seventy....?" and he got right on track with 71, 72 and so on. We never did count to 300 last night because there was a lot of fanfare when he got to 100 - screaming, clapping and jumping may have been involved.
