I am also a stay at home mom of 2 kids. I had this problem when I had only 1 child. I would sleep like 10+ hours at night and nap when she napped. Once my son came along I couldn't get enough done when I napped. So I stopped the nap time for me. It was hard at first, especially when I had med changes (I started meds when my son was 3 months old.) But when I stopped the naps and tried to lessen the amount of time I slept at night, I started to feel alot better, my depression (im bipolar) eased up and I was able to focus a bit better. (When I get only 9 hours of sleep). I hope it helps to know you aren't the only one.
