Milk supply dropping?

Jenna

My LO will be 8 monthes old and I’ve noticed a significant drop in my milk supply. I’ve started feeding my baby 2-3 meals a day in solids, he’s been wanting to nurse less and when he does he bites me almost everytime now, I’ve added a couple pumping sessions after feedings when he naps and can only get a couple ounces out when before I was able to get 6+ I’m not sure how normal this is and I’m just wondering if any other mommas is experiencing a drop in supply due to introducing solids and what you have done about it if so?
