My granddaughter was getting severe leg cramps at night. She would wake up and scream and cry that her legs were hurting. If you rubbed them she would calm down. Now she seems to be getting them in the middle of the afternoon. My son said the other day she just started screaming and crying and went to the floor saying her legs hurt. Any ideas???? They are going to talk to the doctor about it but I thought if anyone else had this problem with their kids they might be able to give some insight on what the poblem might be
