Growing up, my mother always told me that the reason families have more than one child is because of selective memory. Brandon agrees; he says that if it were up to the males, they'd have one, realize it wasn't worth it to have another one, and stop.
Having now produced two, I am inclined to believe my mother. With Sophia only two and a half weeks old, one would think that the memories of being pregnant and giving birth would be fresh, fading only with time. However, I think that a hormone is administered at the hospital that fades everything previous to going home after the birth to a shadowy memory, never to be thought of again. Yes, I vaguely remember something about being overly large and uncomfortable, but you will have to ask Brandon for the details. He still remembers.
In addition to amnesia, having a new baby also dulls one's sensitivity to lack of sleep. Sure I woke up at 12:30, 3:45, 4:15, 4:45, 5:30, and 6:30 this morning, but hey, clearly the sleep deprivation isn't keeping me from doing laundry, reading Kathleen untold number of books (half from memory), and writing this post. Well, I can't make much claim for the post.
But, as with the memory of pregnancy fading, the memory of having a new baby will fade also, only to be remembered all too well by my husband. However, as he is not the one who will do it all over again, his memories won't make much of a difference.
