Milk supply

Shauna

So within the last two days my milk supply has dropped drastically. I nurse LO in the middle of the night and the morning and the rest of the day I pump since he is at daycare and I work. Usually I can get 2.5-4 oz per breast every time and now the last two days I will be lucky to get 3oz all together. What could cause this to all of a sudden happen? I pump every 2-2.5 hours a day so it’s pretty often. I have a ton of milk saved up but I’m not ready to stop yet😫
