An Endless Birthday Loop

If you ask Fiona how old she is, she'll hold up two fingers.

Ask her how old she'll be on her next birthday and she'll hold up three fingers.

Andrea's birthday is on Saturday. When I told Fiona that Mommy was going to have a birthday, she said "Mommy's going to be two!"

So I asked her how old Mommy is now. Fiona replied by holding up three fingers.

So there's your toddler theory of aging: sometimes you're two, sometimes you're three, and I guess on each birthday you switch to the other one.

Does that mean every other year you get to be terribly two?
