Most pediatricians order routine urine tests when children get to be around five
years of age. Although it is easy to collect urine specimens from boys, girls
often have difficulty placing the cup between their legs. You can make this task
easier for your daughter by having her sit on the toilet backwards. When a girl
sits in this position, the toilet seat not only pushes her knees apart, but
there is also more room between the back of the seat and the child’s bottom to
“catch” the specimen.
