Tan, the magicall can be used as is. The extra insert is if you need extra padding. I don't really use it atm, but I will put it in if we're going out for a long trip and I need it to last longer.

With the BG, the smaller insert is for newborn size or for extra absorbing if need. On the larger insert, I put the fold to the back because that is where she always seems wettest.

Normal powder is fine as long as it doesn't have the softers or added enzeymes. I use the Planet Ark brand.

Have fun with your new nappies!
