DS (2yo) has keratosis pilaris absolutely covering his upper arms and thighs and has had it for a year or so. I know it isn't uncomfy because I often have it mildly on my upper arms. His pediatrician just said I was right and dismissed me when I asked him to confirm that it was kp. I know it's no biggie, but it's getting worse. Anyone have any home treatments that work to lessen severity?
