I think u better try not to feed baby yourself, my sister have experienced before, 佢抱住 bb 餵奶粉, bb 唔肯食, 因為 bb 嗅到my sister 嘅人奶味呀, 後來佢搵 daddy 餵奶粉, after 2 days, she started to 餵奶粉 again, of course, for the first time, bb feel a little bit strange, but after few days, bb get used to it & now he is a 奶粉 baby
