To not give my 14yr old the biggest bedroom in the house?

[sashamichele]

I'm a single mum to 4 girls 17,14,5,2 and a son 19. We live in a 4 bedroom house.
The bedrooms are all different sizes there's a box room which will fit a single bed, bedside table and a chest of drawers or a desk.
The next size room is bigger but but an awkward shape but would fit a small double bed, desk and drawers.
The next one is on the other side of the house and is a good size and is mine, theres a king size bed, wardrobe, chest of drawers and a tall skinny bookshelf and bedside table.
Then the 4th is the biggest but not overly massive but the biggest of the 4.
At the minute DD's 14 and 17 share a room and DD's 5 and 2 but now there box room is going spare DD's 14/17 want there own rooms which is understandable so we're swapping round rooms. Dd 17 is going into the second room which atm DD's 5&2 share. So that leaves dd14 in the biggest room of the house and she wants to stay put and let the two little some go into the box room with a bunk bed.
Aibu to tell her that the little ones need the biggest room as they share? She's kicking off about it.

I’m not a big fan of “because I said so” from adults, but there does come a point after reasonable discussion, for telling a 14 year old to suck it up and get over it.

I’m sure it will all settle down soon

FFS, the level of censorship on this site is getting ridiculous. I'm not sure what the point is of turning every thread on AIBU into a virtual doily.

Sorry for going off-topic, OP.

17 year contributes and has already decorated her room. Op is an adult, paying the bills and deserves a decent bedroom. 14yr old still has a decent size room, just not the largest. The little ones get a larger space as there's two of them. No brainer really.
