Sorry, not much help on the toddler bed transition issue but my son will be 22m when our next bub is due and he just doesn't seem ready to move to a bed so we're keeping him in his cot (he's all over the cot at night too!). The baby will go in a bassinette to start with and then we'll get him a cot that converts to a single bed. We figure doing it that way will be the least amount of stress for all of us
