Any April moms in a similar situation?

After returning to work at 3.5 Months pp, my milk supply has faced a downward spiral ever since. I’ve done everything I have deemed possible to increase my supply. My baby rarely breastfeeds, due to lack of supply. I now only pump 3 times a day to provide about 2 feedings. I am having a hard time coming to terms with stopping altogether as I know breastmilk is best for my baby.

Anyone with words of wisdom? Relation? What made you decide to stop if so?
