Im not sure if you are suppose to or not, but my DS slep in his pram basinette beside our bed for around 3 months. Ours is a soft bag type of basinette and it was only for night sleeps. I would put him in his cot during the day. Although there was a lot of room in there for him, I still use to worry about his facing turning into the sides. Not sure if we will do this again for the next one or hire a proper basinette.
