I took in my sister's chidren when she passed away and had 2 of my own. My children are self sufficient, one is 18 the other is 12 and are not always home. I need the occasional break from my niece (9) and nephew (14) whom I have full time.
Literally just be here to watch them and call me/or 911 if needed if I'm out on a date, or staying overnight somewhere (not often, and planned in advance) I'm a single mom, my mother lives here full time as well but is unwilling to watch the kids.
