Talk to Gynecologist on Frequent Urination

My 2.5 years old daughter urinates about 15 to 20 times a day. She is very well toilet train and has no other symptoms. She is active and there are no symptoms of UTI as well. But her frequency doesn't sound normal to me. She poops also alot since birth and doctors never took it seriously but i always felt that she poops more frequently than other kids and now i am observing the same with urine. i am also very exhausted by taking her to the washroom every 15 to 20 minutes as per her demand. Please tell me if it is a matter of concern.
