Peeing Time

The brat has developed a very bad habit. Whenever someone needs to use the washroom.. she wants to use it too… irregardless who it is.. needing the washroom. But everytime, she goes .. she does have pee.. so what do you make outta it..?? And it has been going on for a few weeks now… and if you tell her.. she doesn’t need to pee.. since she already did.. 15 mins ago.. she would start crying. Should I be worried..?? should we bring her to a doctor..?? Doesn’t seems like UTI to me.. ??
