Tell you what, judge away.
In our case the first time dd was 6 months old. We went to Malta and tried taking her with us to eat. She was tired and cranky, most restaurants didn't open until late and so when we tried to have a meal at 7pm she would scream the place down so we didn't enjoy our food and spent the time alternating her between myself and dh whilst the other was able to quickly stuff a bit of food in.
So we put her down in our hotel room the third night and put the monitor on. She went to sleep at her usual time, peacefully and happy. Dh went downstairs to listen to the monitor just to check that he could hear it. During this time I crept about the room just grabbing a few things before heading out. He heard all of this.
We stayed in the hotel and had a lovely meal in the restaurant. Every half hour one of us would just double check our room. It was a much more relaxed experience.
We have done it with both a couple of times since.
I also spent 2 years living in France where their attitude is completely different. We would pick up our kids from school every day and I knew some of the mothers had young babies but they would arrive to pick up their kids without the babies. When I asked where they were, they would reply quite casually that they were at home asleep.
I would not go this far, but to these mothers that was perfectly normal and accepted.
I think that unless you are in that situation you cannot judge. As parents we all take a few risks every now and then but not without making sure that risk is an acceptable one. For me, the risk was acceptable because we could hear her breathing and could hear every sound when one of us went up there to check on her, including the door being opened, footsteps etc and that was us being really really quiet so as not to wake her.
But according to some posters this makes me an unfit mother and on one of these threads I have been told by a couple of posters that they would report me to social services. Yet here I am, calmly and rationally explaining why it's less of a risk to me whilst other posters clutch at their pearls and condemn all those parents who do so to the pits of eternal bad parenting.
I wonder who is the more reasonable?
