Hi mummies, my lil bub is 4 month old and is drinking 90ml in infant care on an avg 3 times a day, when we are home i direct latch. Previously she was only drinking 80ml and i have just increased to 90ml 2 weeks ago after my massage lady commented that my bub is drinking too little. The teachers feedback that she was slow drinker and suggest to change bigger teat. should i change to bigger teat and risk being rejected by bub? should i increase to 100ml per feed?
