Well, I managed to go all day without formula supplementing. I did have to make one bottle last night to supplement one feed because I knew he wasn't getting what he needed (he had been crying and getting really frantic for over 15 minutes at that point) but he only needed about 3 oz of it to fill up after breastfeeding instead of the full bottle so I'm feeling good!! Poor guy is still constipated but I'm sure once his body readjusts to having primarily breast milk, he will be fine 😄
