Breastfeeding mommas help⬇️⬇️😞

Katelynn • Boy mom x2💙🧸

My son is starting to refuse his formula but I can sense that he wants breastmilk.. he grabs my shirt and bites but he cant see or feel my nipple through the shirt/ bra so my question is, how can I get my milk supply back. Also, my son is 8 months and I breastfed until 3.5 months
