Debating whether I should stop pumping

Lately I have been debating whether I should I stop pumping and switch to formula.

I have been pumping for 6 months. I pump anywhere from 6-7 times a day for 20+ minutes. 3 pump sessions while he naps and 2-3 pump sessions during his nighttime sleep.

Sometimes I think if I didn’t have to pump then I could workout while my baby naps. Or nap while he naps! How I could just go back to sleep after his nighttime feed rather than staying up another half hour.

But then I think how I’m being so selfish to not give him breastmilk when I know that’s what is best for him. (Yes, yes I know fed is best). If I stop I would be putting my own needs before his.

I’m sure some of you ladies have been in the same situation before or maybe you’re going through it right now. Thoughts?
