Do I have a baby no one told me about?

Chris got the mail today...

And came upstairs to give it to me. Apparently I got a package...

Inside it was 2 cans of formula. Formula for a baby. A baby I am quite sure I don't have. And the letter inside was talking about the baby I just had, and how every new mom should try this formula.

So I ask, because I know I have been working alot of hours, did I give birth? Was I in the hospital?

What in the world is going on? LOL
