I am curious how you keep clean fresh water flowing into the Puj Flyte when the drain holes are so high up on the product (i.e. they do not allow the dirty water to drain out without getting dangerously close to a newborn's chest/chin level). I think this is a brilliant product, but am having trouble using it b/c i don't want my baby sitting in sudsy water that she may have urinated in. Thoughts/suggestions? I'm trying to find a full-length video of the Puj Flyte on YouTube but can only find videos for the Puj original. I can't use the Flyte in my kitchen sink b/c it's too small in comparison to my large sink.
