I HAVE A BELLY BUTTON

I have a belly button.
You have a  button.
Everyone has a belly button.
However, Missy has somehow developed the idea that if you have a belly button,
man, woman ,child or animal , then you are pregnant!
It can  be VERY embarrassing when Missy spots anyone who is overweight and says BABY!

So, I am looking for Early Learner books that might help bring some clarity to the situation.
If you know of any such books then please let  me know.
I will be truly grateful :)
