These pants are awesome! We use them as a second layer for bundling up. Our daughter is 15 months old and goes to a nature-based day care, so she needs layers for colder days. We ordered size 86/92 in grey melange and they fit perfectly over pants and a cloth diaper (fitted + wool cover). The stretchy waistband is nice to keep the tummy warm, and the cuffs are great for putting over boots for a snug fit. I don't have our daughter's weight/height offhand, but she's very average size. Very sadly, we misplaced these pants a couple weeks ago and have been struggling without them!! We have a different pair of wool outer layer pants that cost almost twice as much, but we much prefer the fleece pants! I'm considering ordering another pair...
