My son is 9 weeks old. 2 weeks ago he got thrush, passed it to my nipples, resulting in mastitis in my right breast. It hurt so bad to nurse and to pump, that I decided I couldn't nurse anymore. After 2 weeks of formula and now that the thrush and mastitis are gone, I want to go back to breast feeding. Is this possible? My breasts feel like there is no milk left, and after letting my son try to nurse today he seemed to get nothing out of my breasts so he got frustrated and refused to put the nipple in his mouth anymore. Any advice would be greatly appreciated!
