Breastfeeding & pumping

I am 32 with baby #2 my first I only got to breastfeed up to 4 months then my supply dried and I gave up and let it cause it felt like baby was never full and always wanting it. This time I’m a lot older more aware but also wanting to pump to increase my supply I want to breastfeed but also pump so sissy and daddy can also feed baby for incase car rides & to also help boost weight loss is this possible or is it only one or the other? I don’t see people talking about this
