Having raised brothers, sister, children, grandchildren and babysat great grand children; I can tell you that you haven't seen anything yet!
If its a girl we are talking about, I assure you that in ten years, you are going to be certain that you are a blithering idiot.
The things get better; within the next three years, others will confirm your analysis that you have become an insane, blithering idiot.
Good luck, best wishes and prayers. Hang on for the most fun you will ever realize.
