Geesh! Personally, I couldn't live with my MIL, so you have my utmost admiration! When my MIL visited us a couple of weeks ago, DH told her we were actively ttc, and she told him we were 'crazy' for wanting another baby because they were so much work! She just doesn't get how much joy we get from our DS. She was barely 20 when she had DH, and I think there is a world of difference between that age and this in terms of what you have to give up to have kids.
