S.W.
D., My daughter had bad leg cramps and pains when she was 4-5 because she grew too fast (the bones did) but her leg muscles did not grow as fast. I had her at U of M in the 70's they suggested a warm bath maybe 2 times a day. Then massage her legs while in the water and after with just a light baby oil, keep her legs covered as must as possible with leg warmers or leggins. She was so bad she was unable to walk for short periods of time this happened maybe 4 different times as she grew up. You may also want to give her a Baby Asprin or Tynol to help her relax at night to get the rest her little body need. Don't forget to give her something to eat to help the Asprin work better.
