Kids are important but they cry, it's what they do.Let me get this straight:
You're on holiday, decide to leave the kids on their own at night after leaving them on their own in a crèche all day because you want to go out and have a nice drink and food (sod the kids they aren't important)
You come back and your kid asks you why didn't you come when they and their sibling were crying?
You really just want to pass this off as: kids cry it's what they do?
You don't think them being left on their own constantly night after night has anything to do with it?
I let them get on with it if they're not in pain
