Hat

If you hear Cole saying something like "Haa haa" it could mean one of two things.

It's hot. (Or cold... the kid can't figure out the difference unless he's pointing at the oven or my flat iron in which case he does know they're hot).

Or he wants a hat.
It's confusing. We're hoping his speech improves before he's 16.

Today though, "haa haa" meant hat. And if the hat you happen to find is your dad's that makes it even better.
