I need advice.

Anyone else kid pee a lot? I have to change My daughter more than 4 times in the night because if not she’ll pee through. We went to town to get my sister some shoes for her try outs and it’s about about 25/30 minutes drive back. Right before she got put back in her car seat I changed her by time we got back home she was almost leaking through her diaper. I’m calling to make an appointment tomorrow to make sure it’s nothing to do with her kidneys. She’s 14m old and in pull ups we are starting to potty train but with her using the bathroom soooo much it’s hard to take her to the potty every time especially since she doesn’t talk or let me know she’s got to go. Any advice? Again I am making her appointment in the morning hopefully she can get in tomorrow.
