L.D.
Hi C.!
My son is now 15, but I remember some of the days as if they were yesterday. One of the things, besides the drops, that helped to give him relief, is I would lay him on the floor (on his back) and take both of his legs, bend them and gently push his knees up towards his belly and hold them there for a few seconds. Sometimes I would take and do one leg at a time for a change in pattern, but mostly both legs at the same time gave him a lot of relief.
Hope this helps....L.
