C: I’m going to have my birthday in a couple more days

M: no honey, not until January. But your half birthday is coming up. You’ll be 3 and a half.

C: oh! My half birthday. And I’ll be just a little bit more 3.

M: then you’ll have your birthday in January, and how old will you be?!

C: 4! And then it will be my half birthday again and I’ll be a little bit more 4.

Well, I guess she has that figured out!
