I advice to go for a documentation with a urine routine examination CUE test. If it is normal, no need to panic. It is only due to less fluids intake. Increase daily intake of liquids to 100 ml per kg body weight and add some cran berries to her daily food intake. If it says it is Urinary tract Infection(UTI) we need a urine culture sensitivity and UTI needs to be treated with antibiotics for now. Later evaluate with a ultrasound KUB and MCUG test to rule out vesico ureteric reflux. This is my approach as a Pediatric Surgeon and Pediatric Urologist.

This is quite normal for babies to cry before and after urination .

Hi. Get a urine routine test to rule out infection. Give plenty of liquids/ water frequently

No need to worry make sure to have plenty of oral fluids . If child having same complaint to rule out urinary tract infection consult with local Pediatrician
