When will my milk supply dry up ?

Andrea

I started to supplement formula because I noticed my milk supply was dropping but I barley make any milk when I pump is my body getting use to not making as much and will it just stop eventually? I’ll pump a few times a day and get maybe 3 ounces in the morning and maybe 2 ounces combined from each boob when I do. I’m eventually not going to make anything and have to do full formula huh ?
