Oh wow, Kialua. That's a long time without a break!
We don't ever ask anyone to watch our son overnight, as he's very close to us and we like to be right there when he wakes up...
But I do appreciate the breaks I get from my MIL and even my own mom, when we just need to get things done around the house, have some time to ourselves, etc.
But I know what you mean about it sometimes just not being worth the hassle.
