Formula Milk / Mixed feed ilang beses po kayo magpadede kay baby ng formula milk? Alternate po ba?

First time mom po kasi ako and si LO ko is 2days pa lang. So I'm planning po mag mixed feed for now habang dpa malakas breastmilk ko. Pwede po ba yun? Thank you so much. #firsttimemama #breastfeeding #formulaadvice
