Frequent urination with only a small amount of urine each time in a child can occur with urinary tract infection , local genital irritation, constipation, increased fluid intake. UTI should first be excluded.
Next Steps
Please mention the child’s age,
how long this has been happening
whether there is burning/pain while passing urine, fever, abdominal pain, constipation, excessive thirst, increased total urine output, or bed-wetting. I would advise to do urine routine/microscopy and urine culture .
Also do random blood
sugar level.
