Advice needed--9 month old

MMW10

Hi ladies! My DD just turned 9 months old, and she's eating 2 or 3 solid meals/day. In the last week or so, she's really started to spread out her feedings, and we've fallen into a pattern of alternating BM and solids roughly every 2.5 - 3 hours. She went through a growth spurt right before this new pattern where she was nursing a TON. So now with her decreased nursing, I am having problems with clogged ducts bordering on mastitis. Honestly, even though I know she wants solids for dinner, I've been skipping them because of this problem. I've had oversupply issues from the beginning, but it was under control until now! Any advice?? I'm nervous to drop any pump sessions or feedings, and I was hoping to start only pumping once/day when school starts again next week!
