Words fail me

These days it seems Rowan's saying new words every few minutes. He's been tossing out "Babige" (Garbage) often, and refers to himself as Wawa. Says "Allo" on the phone, "Oh-oh dow" when he drops something, and "Oh-oh Maash" (Mess) when he spills something.(That last is used VERY often.) And "Tata" is Santa ( a hot fave.)
When it snowed for the first time this winter a few days ago, he looked at the snow and said, "Vow, no!" (Wow, snow!)
Oh and the singing! He "sings" 2 songs so far:
Row row row your boat: Wao wao bot
