DM had my DD today - 4yrs. She let her go upstairs to the toilet on her own while there was a decorator in the room next to the toilet. Obviously she cannot lock the door so potentially the door could have been open the whole time with a half naked child on the toilet. DD told us when we get in from work that she'd had a chat with the decorator on the landing.
No bad came of it, granted. But when I've mentioned to my Mum that I'd rather she went to the toilet with DD if there was a stranger in the house, her reaction is to say that its fine because the guy has his own kids, she was downstairs the whole time and then put my brother on to tell me that I'm being silly about all. We don't really know this man, and even if we did, I'd rather my toddler wasn't put in a vulnerable position.
Am I being silly?
