Girls, do your kids have cracking joints? Didn't see a pediatrician this month. They were never that bad before, I didn't pay much attention. Now it's constant. Knuckles, elbows, knees crack when changing diapers. We had a massage session, but the masseuse said nothing. We're taking vitamin D in a dose of 1000.
