The age old question that every parent dreads getting asked.
The average kid begins to ask that question between ages 6-8. My daughter is 5 and a half and she didn't bother to ask. She drew her own conclusions, and, when you think about it, she's really not that far off.
Miranda's Baby-Making Theory
(get's cut off because my battery died but all she said after that was "...baby out. The end.")
She only missed the mark a tiny bit with the "pea" on the "conveyor belt". She came frighteningly close on the "magic potion" supplied by the dad. A little closer than I am comfortable with! And the baby coming out of a "secret door". I guess only the daddy knows where the door is!
Her 3-year-old brother, Jack, took a stab at it too but he pretty much copied his big sister.
Baby-Making Theory (Jack Re-mix)
His incorporates some kind of baby store. However, he was right about one thing. When you use the "door" twice, that's it. No more! At least in his mom's case! The baby-making door (and the store, for that matter) is CLOSED!
Where do you your tots thing babies come from?
