Hi I'm new to MN but need some advice please about DS. He's 6 weeks old and has been sleeping in a cot at the side of my bed. But for the last 2 nights he's refused to sleep in it and has screamed until I've brought him into our bed. I'm not sure what has changed as before he had been quite content in his cot, and had only been waking to BF 3 or 4 times a night... Has anyone experienced anything similar?
