If I stopped breastfeeding can I start back up?

Alexis

My milk supply went down a lot in the beginning of December and because I had to give my baby more formula I wouldn’t breastfeed a often. Now my milk supply is super low and I’m wondering if I do want to start back up, is that possible? Am I able to get my milk supply back up after it’s decreased so much to where I’m making barely an ounce? I’m so sad I let my milk supply get this low.
