17 months might be a bit young, but only you know what she is ready for. If you are concerned with the height of the bed, you can always try to place the box spring and bed on the floor. You can also place guard rails on the bed. As for her running around in the middle of the night you can place a gate at her door and she will have to call to you should she want out or you can place the gate at the stairs to avoid accidents.Toddler beds are at times a waste, they are a crib with fancy decor and if that's the case, why bother taking her out of the crib.Good Luck no matter what you choose.
