i really can't address that question since i do not know anything about your ten year old --- such as medical history sex of your child fluid intake family history of diabetes possibility of a urinary tract infection (common in girls; rare in boys) etc. i would suggest that you see his or her pediatrician -- someone who knows your child -- for an evaluation and at least a urinalysis.
why is my 10 year old goes to the bathroom 5 times or more before going to sleep?
