Meet a lactation consultant as this problem needs detailed guidance till solved. Don't worty. He will start taking breastfeeding in a while.

I hope he can take feeds from breast as soon as possible, if he wants. Meanwhile empty your breasts completely atleast 6-8 times per day to continue milk production  as emptying breasts promotes production.  Not emptying causes low milk production as hormones will not be produced as earlier. Consult lactation counselor if you want to continue breast feeding. You can use nipple shield meanwhile to help you heal your cuts But donot worry too much. He has grown well and if restarting  breast feeding donot workout, it is okay...continue feeding your child atleast 6 times per day with semisolids and solids as advised by your pediatrician.  No need to feed other milks like formula or cow milk with bottle and nipple. They can cause more harm if proper cleaning of bottles is not done All the best
