Cornstarch on Cloth Diapers? (Diaper Advice)

Lately, I’ve been seeing a question pop up a lot from cloth diapering moms.  Is it safe to use cornstarch on cloth diapers?

In a nutshell?  Yes.  But, as always, there are details, et cetera, to consider.

When Cornstarch on Cloth Diapers is Fine

When you’re doing your normal diapering routine, it’s perfectly fine to use cornstarch on cloth diapers.  It’s a great way of absorbing moisture to help baby stay dry.  This is especially important when it’s summertime or when your baby is in the beginning phases of a diaper rash.  It’ll rinse clean, so cornstarch on cloth diapers won’t cause a residue build up or contribute to diaper funk issues.  It’s also relatively cheap.  You can also get travel sized cornstarch baby powder to keep in your diaper bag, so you won’t have to worry about mess.Cornstarch on Cloth Diapers?

When Cornstarch on Cloth Diapers is Bad

There’s one really big and key time that you should absolutely avoid using cornstarch on cloth diapers: when dealing with a yeast rash.  Yeast is a beast.  It can take a while to treat on both the baby and the diaper stash.  Cornstarch is a carbohydrate (just like the flour that we use in baking), and the yeast will feed on it and get worse.  In this instance, it’s not so much that cornstarch itself is a bad thing for the diapers (because it’s not), but the natural flora that lives in your baby’s gut has managed to escape and start thriving on the skin.  Until you are absolutely certain that the yeast beast has been vanquished, avoid cornstarch, flour, or any other carbohydrate type treatment on the bum.
