FTM HERE 😬😬

My baby girl is 5 days old and has been mainly formula fed due to lack of breast milk supply. All of a sudden i have started producing 1oz from each boob! And leaking quite a bit in between pumpings. (Which by the way is very exciting for my boyfriend and i! 🕺🏾🕺🏾🕺🏾) the issue now is I have almost a full can of unused similac formula that is no longer useful....at least i think. With each oz of breast milk can i mix in a scoop of formula or should i just toss it???? Or is it okay to feed her formula sometimes and breast milk sometimes???

I’d really hate to waste it 😭
