Query: Great concept, but not as useful as I hoped.

I think the concept of the peepee teepee is a good one. However, in practice, they don't really stay on very well, and at best, simply divert the "flow". If all you can really do is redirect your baby's pee, than an extra diaper, wash cloth or even a wipe will do the job. As cute as they are, we're just not using the ones we bought. I do think I'll stick them in my diaper bag, though... just in case I'm running short on wipes.
