We had a night nurse for 2 weeks as a present from my FIL for our second DS. DS1 is not yet two so we were really grateful for the chance for a bit more sleep! However, last night (after ten days of being in our house) both myself and my husband were woken at 5am as DS2 had been screaming for some time. I went into the room after knocking and the night nurse was fast asleep, whilst DS2 was in the Moses basket face down and unable to breathe properly. I called her name but she didn't wake up! I didn't know how she could sleep through as we could hear him from the other side of the house.
My husband confronted her at 6 and asked what she had been doing, her excuse was that he had been up and very unsettled until 4 am so she'd fallen really deeply asleep. She promised it hadn't happened before. My husband refused to pay her for last night and asked her never to come back, but should we have paid her for last night?
