I told her the lactation consultant said there's no need to. When old people heard its advice by a professional, they tend to believe. I brought her to free talk on breastfeeding and baby bathing by lactation consultant in Mount Alvernia during my hospital stay after childbirth. When baby is sick and she has concerns, we visit pediatrician together and i translate what the pediatrician says to her in mandarin so she hears it first hand. I asked directly whether baby needs glucose and pediatrician says no need to so she hears it from him. But if you get a misinformed pediatrician then erm I've nothing to say haha. We had a breastfeeding unfriendly one at first who asked me to give baby formula milk so we switched pediatrician. Im lucky that my mother in law is pretty accepting to new ideas as long as its for baby's welfare.
But when baby is born, being anxious, hearing baby cry, fuss, hiccup and so on, they will still use their familiar method and ask me can they feed him warm water etc. we have to be very very firm at that time. I said no every time they ask so they know no means no. It's difficult to be firm being a new mother and being emotional after childbirth but I have done my research before hand and to me, information is king. I know what I'm doing is correct so I stand firm. Now, they are very positive about breastfeeding because everyone says their grandson looks chubby and healthy. Very glad I didn't give in!
