Hmm, the hardest question i have ever been asked.. I think it would have to be:
Do you want to cut the cord?
asked by the doctor that performed the C-section when my son was born..

Now, i don't have a fear of blood or anything like that. It was my son's birth, i was there, and i was nervous, and excited, as all hell!!
I said no. Simply because i was afraid that i might slip and screw something up..
after all, at the time of birth, everything is coated with a liquid. And slippery as well.. Put me in an emergency situation where i would 'have' to do it and i would without hesitation. But this was that moment when he, my own son, was being born.. It was different..
But i did say yes when the doc asked if i wanted to see the reason she had to have a C-section.. Nothing like seeing the insides of a female on the table (she still hates me for that)
Now, i will say this... If you guys ever get the chance to be there when your child is born, DO IT!!!! It is the most interesting, exciting, life changing moment that you will ever have!!
