Hello - My 7 year old granddaughter s wrist crack continuously. I believe it is causing her discomfort and is becoming very self-consciousness of it. When I take her hand she ask me if I m okay with her wrists cracking. Her parents have asked my granddaughter s pediatrician about this, who said it was nothing to be concerned about. Her wrists started cracking or catching about 7 months ago (6 years old). She did not have any symptons of flu or anything when this started. Her left wrist is the worse. Also, she is a picky eater. She will not eat most vegetables and meat is only chicken tenders. We do have family history of rheumatoid arthritis, which is a concern to me. I do appreciate your input and is there anything nutritional, etc... that can be done to help my granddaughter. Thank you.
