Ah but look at the attitudes on this thread MrsMushroom - some would presumably be happy for their child to go off with a friend's dad who they didn't know rather than stand accused of having paedo hysteria. Yet get them on a thread about using baby alarms in hotels and suddenly they are screaming child abuse!
But again, everyone has different experiences which shapes their judgement.
imnotmymum - same here. Although at dd's first sleepover I got a sharp shock. I knew the mother quite well, she had a lot to do with the school and was well thought of by other mums and teachers. I also had met the father a couple of times and thought he was ok. I had never been to the house, but I knew where it was.
dd was asked for a sleepover at this friend's house and I agreed. I had their numbers and they had mine. They collected her from school - I was there to take her bags from her and give her a change of clothing. All was fine. I went to pick her up the next day and couldn't believe what I saw when I stepped into the house....
....wall to wall animals. Tropical lizards, snakes, spiders, fish all in tanks. Dozens of cats as well as 2 dogs. Hamsters, rats, etc. The house stank and was covered in hair with flies buzzing round the kitchen. I was horrified.
I now know the family slightly better and I know that they have a different way of life than mine. Their standards might be different but essentially they are a good hearted family and dd has stopped over only a couple of times since. But it did make me realise that people can still surprise you. You might think you know someone, but do you really?
I now make sure that I've visited their homes before I let my kids go on any other sleepovers - and I am on first name terms with both their parents.
