My LO only wants to bite me

Na

My LO is 10 months old, i really cantbelieve I made it this far with breastfeeding. Lately we been giving him a combo of formula and breastmilk because I was running out of my supply. Now it's been 6 days since last time I nurse because he wants to bite me. I been pumping like once or twice a day because I'm very full. I will like to stop my milk from coming down and I'm getting a lot of foremilk. It's that ok to give the baby still?
