They didn't create those kids! If you can't afford to pay a babysitter w/o relying on your present kids, maybe you shouldn't have more kids until you have that figured out. That makes me so angry seeing a child's childhood snatched because their little lives are wrapped up in their siblings. It isn't right!
i don't think its a big deal once in awhile.. My neighbor is a single mom with 5 kids, she is NEVER home. the older 2 kids ( 14 & 13) are CONSTANTLY watching the others (10,8, 6) she lays around the house all day & then usually about 10 mins before the kids get home from school, she leaves. I have a problem with that. when she is home & the kids are around, she is usually sleeping so they even babysit themselves when she is home too.
