My pediatrician told me to take it slow, and when they start to climb out of the crib, to put the side down so that it'snot that far of a drop. My middle child took almost until her 3rd b-day to want to be in the toddler bed (we started at 25 minths), she loved her bars. Now, we are close to getting the twins(22 months) toddler beds. They don't even try to climb outof their cribs even though I know they could do it. They climb up to the top when it's time for bed. they are just good babies! ANYWAY, I really did just let the middle one set her own pace, We had it put together with new Dora bedding, and I asked her every night if she wanted to go to sleep in her big girl bed. After the first time that she tried it all night, there was no going back.
