breastmilk to formula milk

Im a breastfeed mom for 1yr ... Kaya lang kelangan ko na mag segway worl and segway study..nahihirapan ako mag breastfeed last check up kinonsult ko na si pedia she still preferred bf wag muna daw ako mag formula. Kaso ang hirap. Pwede ko ba ibypass ung advice ni pedia and magmixfeed muna for a while, if yes.. pede po ba humingi ng tips mga momsh. 😭first time mom kasi wala ko idea how to mixfeed
