E.B.
I suggest waiting. My daughter moved to her "big girl bed" which is a full size (using the crib as the headboard/footboard) and we skipped the toddler bed when she was about 34 months. Just shy of 3 years old. In fact, we tried the toddler bed and she wanted it back to her crib (it's not really any different and doesn't feel like a big change.) She LOVES her full size bed (and so do we because we can all lay on it and read.) We are still working on her staying in the bed and not playing so much but we use a tension gate at her doorway to keep her inside. She has adjusted well but mostly because I think we were able to reason with her easier than we would have at 2 years old. Don't rush it...wait another 6 months or so unless you are afraid of her safety by climbing out. My daughter never attempted to climb out.
