New cloth diapers should come with specific instructions on everything you need to know about cloth diapers, not just the care of the brand you just purchased! They don’t. And no one agrees on anything. So the best that a new cloth diaper parent navigating the shifting landscapes of shoulds and shouldn’ts can do, is study up on vocabulary so they can at least understand what everyone is arguing about.

The Need For A Cloth Diaper Glossary

What is needed is a cloth diaper glossary full of terms lest a facebook group, well-meaning family, doctors, and Reddit groups leave dad and mom both dumbfounded. So we’ve created just that, a new cloth diaper lexicon boiled down to the essential terms. This list is by no means a complete rundown, however, it is enough to get you in the game!

Once you have made the decision to cloth diaper (or an in the research period) you will most likely happen upon cloth diapering communities on the internet. These communities can offer great support and information for the newbie. However, it can be a bit intimidating at first.

I will never forget the first time I entered a cloth diaper forum and began searching the posts. I started to realize that these mommas spoke a different language than me. Many times I was left thoroughly confused about what anyone was talking about because of all the abbreviations.

Many newbies are afraid to ask what certain terms mean so instead either get frustrated and leave, or spend hours on end trying to decipher this cryptic code themselves. Lucky for you I am here to help! I have compiled a list of common cloth diapering and parenting terms used on many forums.  So here we go!

The diaper sprayer basically consists of a hose to carry the water and a hand-held sprayer. On my diaper sprayer, there is a small lever, where the diaper sprayer connects to the water line, which controls the amount of water that comes through the sprayer. There is also a small button on the hand-held sprayer which is held down to actually spray the water. In addition, there is a small hook that can be placed above the toilet to store the sprayer when it is not in use.
