Confused

A

I’ve been breastfeeding my son and all has been going pretty well. He’s gaining weight and sleeping more each night. I just came across something about pumping and now I’m confused. If I’m breastfeeding my son do I need to pump at all if it’s going well? I use the haaka pump while feeding him to collect my letdown but it’s not much but I’m not sure if I should be pumping with my electric pump while feeding him or in between feedings.
