DD is 3 months. I've been combination feeding her from when she was 5 days (on the advice of the midwife as she lost a lot of weight and was too slow in gaining it back).
I usually breastfeed her on both breasts, then give her a bottle and 2-3 times a day I try to express milk as well. This has been working fine so far even though it is quite time consuming. She is growing well and tracking her weight centile.
However, for the past few days she has started to reject the breast. She sometimes drinks from the left one but never anymore from the right one. She cries and turns her head away. It's frustrating for both of us and kind of messes up my entire routine. I have stopped expressing thinking that she might ght feed from the breast soon so am worried about my milk supply. So I'm thinking of switching to exclusively bottle feeding. I'll try to pump for as long as I can but even now I get rarely more than 20-40 ml from both breasts so it will be mostly formula.
I think bottle feeding will have lots of advantages but I'm just wondering if I need to try harder or for a bit longer with breastfeeding. My main reason for wanting to bf at this point is so that she can get COVID antibodies from my COVID vaccination (and hopefully to other illnesses as well.) I don't trust that the antibodies will be preserved in expressed milk and I think that once I stop breastfeeding my milk supply will soon vanish anyway.
What would you do?
