How to wean with picky eater. HELP!

My daughter will be two in a few months and as much as I love our connection I think I might be pregnant and need to have my body back.... I wanted to wait to get pregnant until I got back in shape buttt.... I don’t think that’s happening😅 I had a placenta abruption when I had my daughter so I got rushed to the hospital to have an emergency csection.

Anyways I can’t get her to like any milk!! I tried cow milk/plant based/almond/ mixing my milk with others and she hates it!! I typically pump for her and breastfeed 5 times in 24hrs but my supply is getting low and I’m just tired! Two years we’ll three years of giving my all to a little one is such a blessing but I’m tired now😩

Does anyone have advice!?
