My child is having high fever for the past 2 nights and the doc have asked me to collect urine sample so we could check if it is a UTI. Any idea how to take a good amount of sample?

I had to do this once and this is what I did - I got my baby to sit on a potty and pass urine. After that, I collected it into the container the hospital had given me. She was already going on the toilet seat, so it wasn't difficult getting her to go on the potty.
