We have switched from the toddler bed to the trundle bed from Chunguita’s daybed. We have the trundle at it’s lowest position. It’s in a corner, with her hope chest at the foot of the bed and a guard rail on the side. Chunguita can climb in and out near the foot, but she prefers to sleep up where the guard rail is.
I think this is a very practicle option. When she is ready for a regular twin bed, we can either raise this one or slide it back under the daybed.
