After 2-3 uses my little one developed this rash all over his back. As
soon as we noticed we switched to another diaper we had on hand
(swaddlers?) and a couple of cloth diapers and the rash started clearing up within a few hours. I
suspect the blue dye. I'm posting this in case someone else runs into
the same issue. We were using Honest Co. and Babyganics before this
without any problems and are now trying Earth's Best, so far so good.
