Ate so much he nearly split his pants

Think of the old "Bust a move" song lyrics
"Ate so much I nearly split my pants"
We got done feeding Lauer his cereal and
when we took the highchair tray off this is
what we found. His top button popped open
and his zipper started undoing! Don't tell
me I need to put my 5 1/2 month old in 12
month shorts already!!!! At least he looks
happy and full!!
