Transitioning from cot to bed - how do you know when? My son doesn’t climb the cot but he moves position in his sleep and can end up horizontal in his cot. When he sleeps in my bed on the odd occasion of an unsettled night he sleeps in much longer because he can move freely without being woken up. Is it OTT to consider getting him a small double bed rather than a single? First time mum and no idea!
