Life and times of Allyson

My son Derrick just turned 10 on March 9th. He is so full of questions !!! Most of his questions are about general life but he really can come up with some shocking ones. He asked me tonight how a baby got into the Mom's stomach ???? I was shocked and did not know exactly what to say. I still think that he is to young for this. I know that he hears all kinds of things at school but I am not ready for this. I know that he will have lots of questions as he gets older but I am not ready to explain some things to him. He is still my "baby".
