smarty pants

i was giving the little guy a bath the other night, and he was playing away. the drain plug is a 2 piece plastic thing that the bottom part fits into the drain, and the top part flexes down or up depending on if you want water to go through or not. the top part came off, and it was nearing the end of his bath, so i just put it up on the ledge to let the water drain. he saw it and grabbed it and i told him to put it back where it belonged. he moved the toys that were collecting by the drain and put the little top - upside down - over the bottom part to stop the water. then took it off to let the water through, then put it back on... so much fun to watch his little brain wheels turning!
