Teen Dsd will be moving in with us soon full time and indefinitely. I won’t go into details but there are obviously upsetting reasons for this.
Currently when shes stayed overnight (which isn’t very often) she stayed in pre teen DD’s room. I know this isn’t ideal and the long term goal was either loft conversion or ‘granny flat’ - we will be deciding and speeding up the process of this but obviously is going to take time.
She needs her own bedroom now though and the simplest option seems to be to put preteen dd in with younger dd, they do get on but she has said she doesn’t want to do this.
She would rather let dsd move in with her but I don’t think this will work for either of them.
Would we be unreasonable to tell dd she has to give up her room and share with younger sister for the next few months?
