BF/pumping QUESTION

Eugenia

I know this is probably a dumb question but I’m a first time mom and a little confused about pumping. I hear that pumping increases milk supply, but if I pump does it increase the milk supply overall or just for that one feeding. I’m exclusively breastfeeding and pump usually before bed, when I wake up and maybe once during the day occasionally, will this increase my overall supply or just my supply for those times?

Thanks!!
