For newborns, what i know is best is to df/bf, or cup specially for milk feed macam medela tu, or using spoon to avoid the possibility of nipple confuse, even the hospitals uses spoon / cup to feed newborns ☺️ If mmg nak use bottle, i’ve used philips natural with teats 0, till my kid was about 3yo still 0 sbb nak mimic bf, lagi slow lagi better so that dia akan rasa lagi best df
