Just received these but so far really happy. My daughter is 18 months and wears a size 5. The 12-18 months fit her perfectly with a little room to grow. I read that babies under 2 shld wear soft shoes for better foot development so we love moccasins. She is waking and running in them very well. They are a nice quality. I was concerned about the potential slippery bottom but so far no issues.
