L.,
My son was 23 months when my daughter was born. I wanted him to be transitioned to a bigger bed by the time she arrived. I didn't want him to feel forced out of the crib. We were given a toddler bed and mattress from a friend and had that in his room from 15 months and on. He didn't sleep in it until he was about 21 months old. I agree with previous responses as to it just depends on the childs personality. Will she sleep in a toddler/big bed without climbing out and running around the room. If she won't then you probably might need to keep her in a crib longer. I might wait and see how things go. You could try converting her bed in the next few months to a toddler bed. Then once she is used to that you could get her a less inexpensive toddler bed or a twin. The toddler bed is a little bit of a waste of money in my opinion. My son is almost 3 1/2 and pretty much outgrew his in less than a 1 1/2 yrs. Good luck!
