Me and my partner have a 2yr old DD. He has a DS (8 yrs) from a previous relationship who stays with us less than 36 hours a fortnight. We have a two bedroom house. Our only spare room is currently set up as his room and our DD sleeps in a cot in our room. We can't afford to move right now and our DD sleeping in our room is starting to become problematic. I want to convert the spare room into a proper bedroom for our DD (the child who lives there). My partner doesn't agree and thinks that we should have bunk beds in there so it's our DD room most of the time but then she has to move out and sleep with us when his son comes to stay. I don't agree and don't think it's fair on our DD to give up her room for someone who is hardly there. My partner is worried that his son will not want to come over if he doesn't have his own bedroom, but he only uses the room for sleeping. His DS has been claiming to not want to come over quite alot recently (which he knows upsets my partner) and understandably it is making my partner nervous. I'm not suggesting that he stops coming over, but simply uses the blow up bed in the living room. Am I being unreasonable for wanting to give our DD her own room?
