Has anyone slacked off on breastfeeding for the first 3 months of your baby’s life?

I use to be consistent on breastfeeding. I think the most I pumped in the beginning until my baby was 1 month 1/2 is 3 oz at the most. Recently when my baby turned 2 months and now a week away from 3 months... I haven’t been that consistent. I feel like my supply sometimes is lower then 3 oz. I feel as if my supply is drying. Could I reverse that and make my supply increase at this point? What do you recommend to boost milk supply that’s low or dry?
