Different sex sleep overs advice.

[Angeliz]

Hi all.
My oldest girl used to sleep over at My Mams once in a while and hasn't done for a while now.
My Mam has asked if they can sleep soon with their cousins. My girls are 6 and 2 and the cousins (both boys) are 6 and 5. They would all be in the same bed.
Itr hasn't crossed my mind till now to think when this would unacceptable.
Any views?

(Would rather have changed my name for this as there was more to add, are we not aoolwed anymore?)

I don't think the sex is the issue, rather the lack of sleep!! Will the 2 year old be able to sleep with the other 3 bouncing off the walls?!!

why is it a problem for them to sleep over together if they are 1. that age 2. related?

No tbh the 2 year old doesn't even sleep through at home. It isn't /hasn't been a problem. Just crossed my mind recently as to when the boy/girl thing becomes an issue.
