Pumping again

Kelly
I've been breastfeeding for 8 months and I pumped for the first like 3-4 months as well for bottles. Gave it up because my daughter refused a bottle, but out of the blue she took a bottle the other night with no fussing! I pumped just because lol thinking it was silly, so I only pumped like 3oz and she took a bottle! She took it from my mom and even from me when I went to go pick her up so now I'm trying to get back into pumping but I can't pump more than 2-3oz at a time. And it's mainly only coming out of 1 boob. I made lactation cookies, eating oatmeal, drinking water. Any other tips?
