Susu formula newborn

Hi mummy boleh suggest susu formula yang okay untuk newborn? Dah pernah cuba dupro tapi berat baby tak naik macam kurang nutrients, lepastu tukar s26 purple baby asyik membuang 8-9x sehari sampai naik rashes dekat bontot dan macam ada kahak kesian dia, tukar similac lactose free tu macam okay kahak takde tapi poo dia macam cair and banyak compared to s26 tapi 1-2x sehari je berak so taktau la okay ke tak similac lactose free tu. Sekarang cuba similac intelli pro poo macam okay tapi macam banyak jeluak pula. Pening dah #firsttimemom #adviceappreciated
