Breastfeeding. HELP

Brianna

Okay so my daughter is nearly 5 months now and she's been eating between 4-5oz my issue is my milk supply dropped for the second time. She was about 2 months the first time I went from get 4-6 oz every 3 hrs to 2-4oz every 3 hrs most times being 3 oz. I finally got it back to where it was 3-4.5oz and a lot of times they'd be extra milk in my breast, but now I've only been getting about 1.5-2 oz and I'm not sure what to do anymore.
