I made some lactation cookies last night and had 2 last night and 2 this morning. I was hoping to see an increase in my pumping output and haven't yet. Did they work for you?

How long do they take to work?

This is the recipe I used and didn't deviate from it other than subbing choc chips for M&M's.
