Fed is best

I have an 8 week old who I have been currently breastfeeding and supplementing with formula. Only one of my breasts produces while the other barely produces an ounce. He currently eats about 3 ounces formula and sometimes I can tell when I breastfeed exclusively during the day it’s not enough. I am thinking about going strictly formula at 3 months for day care. I am all for breastfeeding but also want to make sure my son is fed. I do feel there is some stigma around formula fed babies and just wanted to get some support/feedback.
