My 12 year old son has Kohlers. He was diagnosed at age 6. Doctors thought by 9 he would be better but unfortunately he was not. He has spent a good part of the last 6 years in walking boots- soft casts and even a wheel chair at one point. Unlike most cases he has it in both feet. Right is the worst as it is the foot bone that collapsed. We have done Disneyland several times the past 6 years with lots of breaks , ice soaks and pain meds. However Disneyworld is a whole other ball game. Since walking and standing on his feet cause them to swell and hurt we are planning on rope drops and fast passes to minimize time he has to wait in line and so forth. I have been reading up on DAS but just don’t know what to do. Thank you all who took the time to read my novel lol.
