We never used a diaper sprayer. I considered getting one at one time, but figured it was just as easy to shake the diapers over the toilet when necessary. A lot of people do swear by them. We are now on baby number two, and I don't plan on getting one this time around either. I think I would rather spend the money on some cute diapers!
