Congratulations!!
Most diaper creams are discouraged with cloth diapers because they leave a residue on the diaper (in the same way they create a water tight barrier against your baby's skin) that can make your diapers repel moisture instead of absorb it.
You'll find cloth diapered babies rarely get diaper rash, so you don't need to put it on as a preventative measure - only occasionally in response to a rash. My son only gets a diaper rash if he is cutting a tooth. He is 22 months, and the last diaper rash he had was Oct when his first set of molars came in.
If you find your self in need of diaper rash treatment, look for one that is made for or at least tested on cloth diapers not to leave a residue. Kissaluvs was a great recommendation, so it Grandma Els (happy heiny tested it).
Then, when you do use it, it is always a good idea to lay a thin fleece diaper liner between baby and the diaper - just in case. They only cost a couple bucks, so we have five just in case. Wash them separate from your diapers if you use them, so as not to mix the cream with your diapers, defeating the purpose using the liner to keep it off your diapers.
As a side note, since you chose AIO diapers, use caution on the bleach suggestion above. There are only a few diaper manufacturers that allow occasional (once a month) use of bleach, most other companies discourage it or say it voids their warranty. You have top of the line diapers, and I don't want you to ruin them!
