Formula intake question


My 11 week old LO used to be a great feeder but he was diagnosed with reflux and cow milk intolerance and since being on the new formula and the past 2-3 weeks in general I cannot seem to get him to have more than 3oz per feed, most times only totalling a 21-22oz per day .

Has anyone successfully increased their babies formula intake? Or is what he’s having normal?

It’s a far cry from the amount recommended to feed on the tin and also less than what the midwife told us he needs per feed.

Any tips appreciated
