Am about to move younger dd into a bed - she's two. Last move (for older dd) was forced by needing cot for younger dd - if you see what I mean. Wonder if this is the right age to move her/any problems associated with keeping children in cots until much older. Have heard of someone who keeps her four year old in a cot to make her life easier - it has a net or something over the top. Must stress don't know her and would never do it but surely that's unkind, at the least?
