Daughter- "what is a uterus?"
I thought for a minute and then said "It is where a baby grows and you even have one on your insides!" She said that she likes the word, and repeated it several times. At this point we were almost up to the drop off point in front of the school and I started thinking that maybe I should not send her in to her classroom saying "Uterus, uterus, uterus!" I can just imagine the phone call from the school I am going to get for this one.
Here are the buttons they wore on the house floor. Incidentally the buttons have been banned too! See here.
