Hi J.!
I have three daughters, and breastfed them all. I conquered anything and everything during my breastfeeding days.
My suggestion is to feed more frequently on the side that produces less. I always learned that the more you nurse, the more you will produce. I always nursed one breast per feeding, but that doesn't work for everyone. So, I would suggest to try to nurse off both sides at each feeding until you notice it producing more. I hope it works!
