Since DD was 4 weeks we have mix fed due to a variety of reasons, including tongue tie and supply. I expressed milk, used formula and tried offering her the breast as well for a while. Dd is now 12 weeks - I haven't offered the breast in a while as it just upsets her now, but about 1/3 of her milk is expressed breast milk and 2/3 is aptamil.
When she was tiny she didn't seem to notice the difference, but as she's getting older she seems to prefer the aptamil. She rarely finishes a breast milk bottle and fusses throughout the feed. Whereas with the formula she usually finishes it and seems to enjoy it more.
I haven't changed anything in my diet, I'm just wondering if perhaps she prefers formula as she has more of it? Does anyone have any experience of this? I work so hard to pump the little milk I'm able to as I know it's what's best, I'm just feeling disheartened. Thank you
