I'm dood it.

Zane, like most kids his age, wants to do many things himself. Like
most moms, I usually let him. It makes me giggle every time because he
always grabs whatever it is (shoe, food, seatbelt, crayon) and
declares "I'm dood it!"

In this picture he decided the umbrella should go back on his sand
table (with the usual declaration). When I tried to help him, he
refused, saying "need MY help!"
