Mini cribs

My daughter is gonna share the nursery with the new baby (once baby sleeps through the night) but the room is small. I’m looking into getting the mini crib but I’m worried she’ll grow out of it before she’s ready for a toddler bed. They’re advertised To fit until baby is 2 but they look so small online so I’m just curious if anyone has had one or maybe knows someone who had one. My girls are tall they told me at the anatomy scan her legs are in the 91 percentile.
