Definitely wear one before it escelates into something worse. take it off when they are napping and after hours if it doesnt hurt otherwise you will weaken the wrist over time. I have hypermobility in my wrists and they are dislocated more often than not so I will wear supports as often as possible to prevent them from poppong out of joint. Hopefully this will go away on its own once your not so little one is more mobile.
