My daughter. Although it's not called a hip click. It's called hip dysplasia. She wore a harness full time for 7 weeks and only at night for another 4 weeks. We went to the pediatric orthopedic doctor every few weeks to check on it and to make sure her hips were maturing the way they should be. Now we go back once a year for an x-ray just to be sure all is well. She's 5 and has zero side affects. Feel free to pm me if you would like
