Does dropping pumps drop supply or TANK supply?

5mpp, currently at 5ppd (630,1030,230,630,1030). I produce 30 oz per day and it’s been that way since the start - I’m ok with that output, and glad I didn’t lose anything going from 8 to 7 to 6 to 5. I’ve been at 5 for 2 months. It’s going fine, but I’ll be excited to go to 4ppd.

I don’t mind pumping, but am also OK with my supply dropping as I drop pumps and supplementing by combo feeding.

In your experience, when you went to 4, 3, 2 pumps etc - did you just slowly lose your supply? Or did it drop and plateau? I think I can easily make it to a year if I get to 2 pumps a day and still produce, say, 10 oz.

Also, I assume his OZ will go down as he gets better at eating solids?
