Have DD4 and DS2.5. They get on well and in the same sleep pattern at present. DD4 is a dodgy sleeper and would certainly benefit from the presence of someone else in her bedroom. I remember in my childhood wanting to share a room with a sibling but not being allowed, as individual space and independence was thought to be important. Instead I spent many nights terrified and remain quite a pathetically scared adult at nighttime.
I’m considering buying a double bed for DC to sleep in but keeping a single bed in DS’s room for if they want their own space. Has anyone had children that bed share? Or did it as a child themselves? I just imagine it would be hugely comforting to them, but not sure if I’m projecting. Any glaringly obvious cons apart from when they’re ill and wake each other up?
