"When is our baby gonna hatch?"

So I had to take both the boys to my 23 week OB appointment which of course spurred a million questions from Noah.  The funniest of them all was "Mommy when is our baby gonna hatch?"  After I explained that our baby wasn't going to hatch it was going to be born, he then asked "How will it get out of your tummy?". Luckily for me I am having a c-section so I simply explained it would come out of my old "boo, boo" and he went with it!  I am so not ready for all of these big life questions... where is the how to book on what to say when to a 4 year old!  Ugh!
