We pretty much explained the "kid friendly" version of what was going to happen to our kids (3,4 and 9). They were going to be spending 2 nights with my mom and we generally discuss everything anyways! I told them the dr was going to put a band around my stomach to help me lose weight to help me eat healthier so that I could lose weight. We stressed with our 9 year old girl that it was a health improvement and not a vanity issue, as she is already getting worried about her appearance.They were all super in helping me recover! Helped pick up their toys, got me anything I needed, climbed into their carseats without complaining since I couldn't lift them. I've been pretty open with everyone about my surgery, blogged about it, etc. So I wasn't worried about them "spilling the beans."
