Cloth! lol, cleared everything right up Super easy to put on, extremely cute, soft and fluffy, good for the environment, and exrtemely easy on the wallet. I haven't had a problem since. Its come an extremely long way from flats and pins. Infact I dont even own flats pins and plastic pants. I own stuff like fitted organic velour diapers etc. But in all seriousness........not a single rash since, and i and my baby enjoy diapertime.
i doubt i can actually convince you to use cloth.....lots of moms are very phobic about what the think it will be like (which is unfounded) BUT here are some other things you can do.
Invest in good butt balms (triple paste is great but $$, also try earth mama angel baby butt balm, and burts bees) Invest in some disposable liners (many are made of rice paper) that you can put between the diaper and your baby's butt (creates another layer between the chemicals in the dipe and her butt) and avoid anything scented or does not say extra gentle hypoallergenic. But in all honesty i would say its a reaction to her wet diapers since she is fine with it everywhere else. Try changing her every 2 hrs and let her have naked time for a half hour a couple times a day.
