Allow your young children to play in MY bedroom whilst playing at my house.
It happens every time I have other children around. One little girl even got out most of my shoes from my cupboard, brought them into the lounge, where i was chatting to her mum, and her mother didn't tell her off.
I had 3 toddlers playing in my bed yesterday!
If my ds1 was playing in another parent's room I would ask him to play elsewhere and if he kept gong back I would put him on the naughty step.
I can distinctly remember knowing it was v naughty to even go in another parent's bedroom whilst playing at friends houses as a child. Has this unwritten rule now disappeared, or do I have rude friends?
