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?

Different babies, different intake. Ask the caregiver at IFC, is your baby generally satisfied after 90ml feed? If so, there's no need to increase feed. And how is your baby's weight gain? Constant on the percentile chart? I advise against changing to a bigger teat. When babies latch, they are able to control the flow of milk. During bottle feeding, it's basically free flowing. Changing to a bigger teat may risk your baby choking on the flow or breast rejection (baby prefer fast automatic flow from bottle). That said, I have also heard mummies upsizing their bottle teat and still able to latch their babies. Still, different babies have different results. I would not risk it if I were you. Hope it helps.
