In an ideal world when would DD/DS stop sharing a room?

[early30smum]

Just that, really. Do you think siblings of opposite sexes 'should' stop sharing a room by a certain age, if possible?

Certainly by puberty (for either of them), and if one of them becomes uncomfortable before that point.

So back in the day when social housing was a thing the cut off point was 11.

When the first one hits age 9 ideally.

I only have boys but eldest ds is 8 and in yr3 and becoming aware of differences and privacy

Probably going to get my arse handed to me here but I have my 2 eldest still sharing at 12 (girl) and 10 (boy). Our 6 yr old is by herself.
However, they chose to stay together, and we check in with them that they are ok with it regularly. They've shared since they were 5 and 3. We've tried other combinations over the years but they all prefer this combo. Obviously if their feelings change then we'll shuffle them about

My two youngest are dd9 and ds7 they have always shared. My eldest moved out about 4/5 months ago we said we would split them up now we have a spare bedroom but ds often creeps back into his old bunk bed or I have even found him cuddled up with his sister in the top bunk many times I think after sharing for so long it will take some time to adjust.
