To think it is socially unacceptable to

[Nooneelseisallowedafergus]

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?

Agree with everyone else - it's up to you to say "No, that's my bedroom and not for you to play in - we're playing in here today" and stick to it. Keep the rule all the time and your own dc will tell other children it's out of bounds.

I don't understand how, if your bedroom is next to the lounge, you just let them go in there when you could presumably actually see them doing it. I think it's rude to blame another parent for not enforcing a rule you clearly don't enforce yourself and that they probably aren't aware of.
