Hi everyone! FTM here with an almost 6 week old. She is currently eating 3 oz of breast milk every two hours. I am EP. I haven’t felt able to keep up with her lately and am wanting to combo feed. Seeing as she takes 3 oz bottles right now, how much formula would I add to achieve a 2:3 ratio BM to formula? 2 oz BM, 1 oz formula? This might be a silly question but I know formula isn’t as filling so I want to make sure she doesn’t leave a feed still hungry. TIA!
