How do i tell my hubby...

That if we ever die, lord forbid, I want our children to go to my parents. they are younger than his mom and there still married, happily. finincially they are much more stable than she is and they live in a house. His mother is divorced and has had one of her children taken from her because of issues with Aderal. She lives in a 1 bedroom apt. I dont want to hurt him but I would roll pver in my grave if my kids got stuck with her.
