Thinking about future furniture for my 3 yo, who is still in the crib for now.

She currently has a twin bed in her room that came with our house when we bought it. I like the head and footboard enough, but it’s kind of tall and has big drawers underneath that are kind of jacked up (previous owners had warned us about that). For now it’s a place to sit and read books before we put her in the crib, it’s creaky, and has an old mattress. I was thinking maybe we can get rid of the jacked up drawers and put a trundle bed underneath for future sleepovers, but the bed is higher than I’d like for a very short 3 year old (literally 2% for height). Are they always tall or just this one?
