Barley is a cereal grain that you should be able to find in your health food section in most supermarkets. If you are lucky you can sometimes get Barley water in the same section ready to go.
I didn't bother using the anti-B creams when i used the Lansinoh as i figured it was so thick the cream wouldn't make a difference anyway. But you really only need a night to see if it will help the rash anyway. so it probably won't hurt to miss one nappy with Anti-B cream IYGWIM Don't forget a liner though if you use your cloth as it will really clog up your nappies.
