I don't look at it in terms of replacement spots. You know... I tried to write this out a bunch of times, to put it in rational terms but it wasn't working because I guess for me it is entirely personal. I do daycare because I love working with kids. I really can't imagine doing anything else. I don't have any of my own and I'm never going to. So what I don't understand is when people have children, why not spend as much time with them as possible?
