I have 2 kids now, and the first 3 months of a kids life really suck. Maybe not 3, but at least 2. All they do is eat, sleep, piss, shit & cry. Your entire job as a parent is just to keep them alive, and that's it. It wouldn't bother me at all if I missed 100% of those first 2 months. Kids start to develop a personality around 3 months, though. The switch in their head turns on. Suddenly they go from slabs of meat that complain all the time into real people with personalities. That's when the fun begins.
