Okay, but guys? Attacking and insulting the OP isn't the way to go about it.
Seriously - when was the last time someone attacking YOU made you think "oh wow, I really ought to listen to that person's advice!"
And it only keeps someone from asking a question the next time... I mean, fear of 'looking stupid' is what keeps most people from asking important questions - and in the end, would you rather the OP ask - and avoid a potential crisis - or just 'try it and see what happens'?
There's no 'handbook on parenting' that tells us how to do everything right all the time - and I know I've made my own share of stupid mistakes, and I'm just lucky there were no consequences.
While I wouldn't leave my child in a cabin unattended, I can see the logic - I mean, 999 times out of 1000, a sleeping baby does just that... sleeps. And for centuries before baby monitors, they seemed to manage to do it just fine even when someone was in another part of the house where they couldn't hear them.
Then again, there's people on this board who think it's perfectly okay to leave the ship and leave their kids in the kids clubs - even though they know the pagers won't reach them off-board. Not something I could even contemplate... but I see why people do it - they trust that the child is in a safe environment.
It's one thing to say "no, don't do it" and another entirely to say "you're stupid or bad for even asking that" about the OP.
One is advice, the other is just disparaging someone who came here for advice.
