She’s 19 weeks. She’s the same, will go on the boob then drink 30ml. Then spend 30min pushing bottle away then take some more. But over the course of the day I’d say about 550/600ml formula which has gone down. So I’m not sure if she’s getting more from me or drinking less.
Formula and breast milk are different, breast milk adapts itself as your baby gets bigger so has a higher fat content etc for when they are growing and need more calories but they will probably only ever drink the same amount so 100ml of breast milk at month one will be completely different to month three for example. Don’t go by what’s on the formula tins they are only for fully formula fed babies as obviously they need more volume for more calories. If you want to keep breastfeeding only ever offer 4/5oz of formula so they don’t get a preference to that. As long as you are having plenty of wet nappies and gaining weight steady you have enough milk 😃. We combi fed too and it took me a while to not have it stuck in my head that that’s what she needed.
How old?120-180ml / per feed. 700-950 ml a day. Mine don’t like to eat a lot in once. So she drinks less more often or a 150ml bottle in an hour. Like she drinks the half then later the other half or maybe less then finish it later or not even finish 🤷🏻♀️ so 600 is ok. Mine is 4 months today. 605ml today until bedtime. I will give one more then hopefully will sleep until morning. Or maybe have one more tomorrow 2am
