I wouldn't leave my child alone, sleeping in a hotel room, but that's because of the way I parent. I don't judge all those patents who don't co-sleep, and I certainly don't judge these parents.
It's amazing how quick most people are to blame the parents and to pass judgement. Most of us have probably been in a situation where our child scared us to death briefly (wandering off, running into traffic, falling badly, almost falling) and where, with the tiniest variation in fate something tragic might have happened. I guess if that case, most of the rest of us would sit smugly at our keyboards and pass judgement on that incident.
bad choice,if socializing without your kids is SO important,leave them at home with your parents for a few days etc or just WAIT a few years until they are older.down time is important to all of us but i would rather have my kids safe thank you very much
