My parents cannot for the life of them understand why I would have more than two. I haven't told them about #4 yet and won't until I am fairly certain that he/she will be a reality. I didn't tell them about our fertility treatments nor my miscarriage. It is weird because we are very close and they adore and spend a lot of time with the kids. I think that they believe too many kids drains too much of my personal and marital time and that they would like to see me have more time to myself and more time for H and I. We have a totally different lifestyle than they (we are much more kid oriented) and they think it is weird.
