You might want to do some changes to her ml but up her number of feedings. For example, if she currently drink 100 ml and 6 times a day of feeding then change it to 80ml and 8 times a day feeding. You may want to see changes if she drinks better. Or perhaps stick to the number of feeding but reduce her ml. Not all babies intake will be the same and not necessarily you need to change bottle teats too. It can also be that it is a growth period that they suck cry kick fussy when drinking milk at times. To me as long as they drink well, not murder cry, not much of bloated tummy, poop colour is good then I am happy. But, if I am in doubt, ill QnA with doctor during check up and ill google where necessary. This is what Ill do even with two kids. Because not all kids are the same.
Hope this helps 🥰
