Thank you for your query
Seems that your girl is developing recurrent febrile Urinary Tract
Infections (UTIs). In that case you should first get a culture and sensitivity of the urine and give her antibiotics accordingly. She should get an ultrasound
of the kidney
ureters and bladder. And she should also have an micturating cystourethrogram done. It is an invasive test (which means she will have to be catheterised for the test) and these have to be done under the supervision of a pediatrician
or pediatric surgeon. It would be helpful to notice the voiding patterns of your child and definitely avoid constipation
as it can be detrimental or at times even a causative factor for UTI.
Hope that helped
