I'm a childminder, I look after two sisters who are 4 and 1. I have two kids of my own (9 and 13) and I sometimes watch friends kids if needed.
On Tuesday, I was watching my mindees and my friends daughter popped in for an hour. She was having problems with her skin and was due to go to the drs which is near mine so waited with me. She's 14. She played with the babies then went off to her appointment.
Today, my mindees dad dropped off the kids, and the 1 year old had a scab on her stomach and neck. He told me it was nothing serious, they'd been to the drs it wasn't infectious, and gave me the cream to put on it. Fine. But later on, my friend who's daughter had popped round came by, and told me her daughter had had impetigo. I showed her the babys scab and the cream, and she confirmed it was the same cream her daughter had.
So the daughter has given the baby impetigo, at the time I had no idea that's what it was, and wouldn't have let her around the babies if I had. Do I mention this to the parents? They've obviously lied to me regardless of the fact that they know me or my kids or anyone else could be infected.
