Candida is easily treated for both the nursing mother and infant. But the bumps are not likely to be from that. It is usually confined to the baby's mouth. Rashes in babies are quite common and the fact that they come and go gives me even more confidence that this is nothing serious. Skin often changes. It is possible there could be sensitivity to a product (carpet cleaning, fabric, laundry cleaners, etc.) so you could try using only a mild laundry soap like those designed for baby clothing (Ivory, Dreft) and if it was carpet cleaner, that should be very temporary. If it isn't bothering her it is likely just normal, but sensitive baby skin.
If it gets worse or does not go away between episodes, talk to your pediatrician about it.
