A riddle

What's new?

Things with which Bug used to share a common feature:

Earthworms
Ducks
Anteaters
Some old people

Things with which Bug now shares a common feature:

Alligators
Sharks
Tyrannosaurus Rex
Lupe


While you're pondering on that, let me talk about Bug's bowel movements.  I know she'll be thrilled later to find that I've shared this with complete strangers the world over:

Eating banana baby food for 2 and a half days makes Bug constipated.

It's like she's a real human or something.

Anyway, answer to the riddle:

Our baby now has teeth.
