Hi Fiona, I hope you don't mind my writing you. I just became the foster mother to my niece who is 15. She has been in foster for six yrs and has been a bedwetter all of her life. I know for a fact that she has been diagnosed with Sickle Cell. Do you know where I can obtain any more information on the relationship between bedwetting and Sickle Cell? Any info would be appreciated. Des
