Supply drop. Need help!

Allison

My baby is just over nine months and has been breast/ bottle fed since day one. My supply is dwindling no matter what I try. (Power pumping, fenugreek, brewers yeast, lactation cookies, Gatorade, I pump every 3-4 hours, oats, flax seeds...) I think we are going to have to start with formula, but I have no idea what to get. What would you suggest? Where do I start?
