"Leave It To The Kids" joke

A three year old walked over to a pregnant lady while waiting with his mother in the doctors office.

He inquisitively ask the lady, "Why is your stomach so big?"
She replied, "Im having a baby."

With big eyes, he asked, "Is the baby in your stomach?"
She said, "He sure is."

Then the little boy, with a puzzled look, asked, "Is it a good baby?"
She said, "Oh, yes. It's a real good baby."

With an even more surprised and shocked look, he asked...
"Then why did you eat him?"
