We have a junior ready bed. DD went into it when she outgrew her travel cot and we have used it loads. Its great, she sleeps fine in it and likes it too so she sees it as a treat. The only problem is, if your DD is in a room with you, it can be quite noisy - its kind of crinkly when she rolls over.
dd has a readybed but she loves her cot..we have dscussed getting her a lovely new 'big girl' bed at home too but she is not happy about the idea yet. We are lucky in that she has been dry at night now for almost a year but also never needs to get up for a wee at night
