Views on this please. I have a 4 year old ds and 19 mth dd. DD sleeps well in her cot in her own room. The plan at the moment is to move them in together when dd is old enough to go in a bed (she is 2 in Sept and we moved ds up when he was 2). DS really wants DD in his room now - they shared a room on holiday and he loved the company. DD is obsessed with beds and keeps wanting to sleep in DS's bed. DP thinks we should just get bunk beds now, and move DD into the bottom bunk with a bed rail. he thinks once ds starts school in september he'll start to get more territorial about 'his' room and 'his' things (not at all the case at the moment) and we should do it sooner rather than later. What do you all think?
