My eldest son (now 16) had growing pains regularly from about 2 until he was almost 10! Late at night or in the morning is when they would come, sometimes waking him up. We finally got into a routine that he would come find me or crawl into bed with me, and I would masssage his calves until he felt better, or usually fell back asleep. We never tried Advil or anything, because he really hates medicine. Good luck!!
