She is on the tall side for her age, I got her size 1 little kids and she can walk and jump just fine with them with a little room to grow. Sole is soft and has a bounce but seems firm enough it will last a while, probably not for hardcore runners though. Some room to grow. I just added some extra holes in them and it was PERFECT. Though I might give the Amazon pillows a try as they have similar reviews and are A LOT cheaper. Three stars because they are plastic and easy to rinse off for toilet training accidents. Otherwise for the price and if you are using it for basic everyday use its great. set. It would be much better if you could tighten the foot to the bar independently of fastening to the roof. I’m not sure how to switch off the party lights during the day.
