Breastfeeding/ pumping help

Me

My LO is 2 months and I breastfeed mainly and give her a bottle of breast milk once a day to make the transition easier for when I go back to work. I’ve noticed lately that my breasts don’t feel full as it normally would, but my daughter has been getting enough intake by tracking her diapers. Is that normal to not feel the fullness as much?

Also, what has worked for other mommies to get more milk while pumping? Currently, I’m eating lactation cookies, drinking lots of water, drinking bodyarmour. Just wondering what has helped other mommies with their breastfeeding/pumping journey.
