Right. I feel the need to clarify a few things here.
"Parents leave their children there- if the children are unhappy hopefully the parents would know and act."
Well not really. If you have a baby/toddler then how do you know whats going on? They arn't old enough to talk. Even if they are happy, doesn't mean they are safe either.
"It isn't uncommon to have chicken pox parties. They aren't my idea of sensible but a generation ago lots of parents did them, it may be she spoke to the parents about the "benefits" and they agreed for their children to play with your daughter when she was ill."
She did NOT check with the parents. We were meant to be visiting. DH phoned to say w couldn't come as DD1 has SW. She replied "Oh come anyway it doesn't matter". DH said no way.
"If the children are old enough to play in a room alone then why can't they? I have never used a child minder but I would be surprised if they spent the whole time in a room with the children."
The youngest is about 10 months. And she is NEVER in the playroom. So the only time they spend with her is when they are eating in the kitchen or need a nappy change or toilet help.
"A child wondered off into the street and she told them off/shouted at them-what should she have done laughed and encouraged them to do it again? Some small children can unlock doors-her style of telling them off would have been fed back to parents one way or another."
No, he didn't unlock the front door. It was left OPEN. When DH brought him in, she was watching daytime TV and she hadn't noticed he was gone. I would expect her to a) make sure the door was kept shut, b) tell the parents as he was pretty shaken up c) Just explain to him it is dangerous and he can't go out the front etc.
"The only thing that I can see really awry here is that she leaves children in the care of people who have not been approved/vetted."
I think this is what I am going to report first, as hopefully, if I give them a time and day she will be out (after a bit of research) then they will turn up when she isn't hope and catch her red handed.
"If as you say other people have reported her in the past then most likely the parents know/have heard about it"
I don't think so as they are different children now.
