I have specifically worked on this with a few girls as OT goals after discussing with the parents what would happen in the school setting and going over social stories to ensure the girls knew this was normal, the special needs nurse and I made individual baskets that were kept in the bathroom cabinet (I would highly recommend this!) the baskets contained sanitary products, spare underwear, and a change of pants. The girls and parents knew and trusted us (another HUGE part) if assistance was needed we went in showed how to apply a pad, made sure good hygiene was used, hands were washed and after a couple of times the girls were independent!
