My milk is drying up 2 weeks pp!

Totiona • I'm 24, Mother to a beautiful little girl and a gorgeous little boy!!
I feel so horrible. Last week I was getting over 3 oz close to 4 from both breasts. Now, I'm lucky to even get 2. I feel like a dang failure. I have to pump because my little guy won't latch. He has a terrible time latching and then gets SO upset because he's hungry and we both are trying and it's not working. I pump every 2 to 3 hours but still barley any milk comes out. I guess I just needed to vent.
