This is my kids raglan pullover, reversible, each side has its own personality. It fits a size L (5/6 years) kid. I knit with local raised Baltic wool spun in Pace where no chemicals are used to wash the wool, just water from the pond. There are still bits and pieces of meadow chaff in the yarn just to prove it. There is plenty of lanolin in the wool to keep the kids warm. I add a few strands of kid mohair to make it super soft and cotton for color and windproofing. This sweater is PREWASHED on a wool cycle and then laid flat to dry. You can go ahead and do the same.
