At what age did your move up from cot to bed? My dd2 has started to show interest in 'proper' beds, she keeps climbing into dd1's bed and making makeshift beds out of cushions in the living room. I am a bit hazy as to when I moved my other two on from their cots, as there is quite an age gap between them and dd2. I am not keen on the idea, as she is not the best at bedtime and at least a cot 'keeps her in'!! But is she is ready I don't want to hold her back. She's 2yrs and 3mos by the way.
