Help my milk is drying up !

I don’t know what happened, we’ve been doing fine breastfeeding I could pump 5 to 7 ounces every 3 to 4 hours, but within the last couple of days I’ve only been able to pump maybe half and ounce a DAY 😞.

I don’t know what I did wrong my diet has not changed, I’m drinking the same amount of water (actually drinking more now to see if it helps), nothing has changed in my life .

I’ve started power pumping to see if that helps and nursing for longer periods of time but so far no change . I’ve had to place my 6 month old on formula because he just wasn’t getting anything to eat from me.

If anyone has advice on how they got their supply back up I’m all ears I’ll try anything.
