Decreased milk

Erin

My supply has dropped drastically and I'm mostly to blame since I didn't commit 100% to breast feeding. I started supplementing early on and now I'm giving mostly formula. My question is, is there any point of return and getting my milk supply back up? I make lactation cookies and it kinda helps. I have a toddler and 3 month old so it's hard to pump pump pump and so much easier to grab a bottle sometimes.. I maybe get 3 oz combined boobs . My right is a complete dud and only have the left that produces... am I just done or is there any chance of getting it back up?
