FOUR-YEAR-OLD QUESTIONS...

So, my four-year-old has been VERY into my incisions and scars on my belly.  She asked me last night, "Where's the cut mark from when the doctors took me out of your tummy?"  (Mind you, I did NOT have a c-section)  So, how DO you answer that question??  I told her that not all babies get cut out of mommy's tummies and she didn't.  "Well, how did they get me out, then?"  As funny as this is (and it was!!!), I had to tell her that I needed to think about how to explain this to her and I'd get back to her later on it.  I KNOW she won't give it up, either!  Any tips??? HAHA!
