No issues with BG. I had some issues with another brand of pocket diapers because I was getting ammonia build up in the inserts. Stripped them twice and the issue went away. You can try coconut oil, it is cloth diaper safe and natural fiber inserts if you have an issue. Some babies are sensitive to microfiber inserts.
Make sure that there is a barrier between the microfiber and baby's skin too. Microfiber will suck too much moisture from the skin when placed up against it too much which will cause diaper rash.
