10 year old with weak bladder

I have not brought her in to our dr yet, but I plan to. I am however looking for other moms that have experienced this with their daughters.

I have a 10 year old daughter that is constantly peeing her pants from laughing. When it first started which was sometime ago we honestly have never thought anything of it. But I feel like now it has gotten worse. To the point when she is away with friends and family we have her pack extra pants and undies because we know it will happen and want to prepare. Anyways, tonight she went to a bday party and it happened twice. She had 2 accidents and unfortunately did not have any extras with to change. But I am now planning to bring her in and have this checked out. Because now she’s just getting too old and can’t continuously be doing this all the time.

Has anyone else had this happen to them or their daughter? Thank you for the feedback.
