Hello Room!
We used to live in my parents-in-law's house for two years and since we only have one room then, we let the kids, Champagne and Charlton sleep on the same bed with us. By the time we moved to our own house, the kids won't just sleep in their own respective rooms. I don't know if they are just scared or if they are just comfortable with us nearby but it is always a struggle every time we put them to sleep. In the end, its either they are in our room or someone is with them in Champagne's room. (Charlton's room is empty as they won't sleep separately)
Just last Sunday, though, I was able to talk Charlton to sleep in his room. I let someone sleep beside each of them as they are still afraid to sleep alone. I think it is a good start. At least, they are now sleeping in their own respective rooms. Just a little more time and they will be off sleeping alone. Kudos to them!
