Basically one of my daughters friends has only just turned 4 and she plays out in the streets all the time. There's no busy road so alot of the kids do of all ages. She will play in my front garden with my daughter for hours and her mum and dad dont come to check on her at all. They can't see my house from theirs and alot of the time they don't actually know where she is because she plays with a lot of other kids too and doesn't say where she's going. Her dad shouts of her when it's time to go in and I've seen her running around outside past 9pm. Today her dad shouted of her and my daughter went around to hers with her to see what he wanted. She then came back 5minutes later saying her mum and dad were going to the shops and she said she didn't want to go so they locked her out the house and told her to play out and if she wanted to get in for any reason to climb through the window. I just feel in my opinion that shes too young for all of that. She shouldn't be left playing outside with no parents there to keep an eye on her. Anything could happen! I told her to play in my garden while her parents were out. I don't think she gets much attention from her parents at all and they just leave her to her own devices. I don't really know what to do with this as I don't really know her parents just the fact that they are her parents. Any advice?
