Dear Sharon, I worked with a mom like this many years ago . She breastfed two children each for more than a year and never had any problem with milk supply. She did, however, have a badly cracked nipple both times. With each baby, she stopped nursing for a short time until the nipple healed (pumped and fed with bottle) and then each baby went back to breast easily and nursed well thereafter ( never did figure out the cause of her nipple problems). There are cultures where babies are routinely nursed on only one breast and they do not seem to have any problems. Go for it.
