Quit exclusive pumping???

My son is almost 3 weeks and I’ve been just pumping and supplementing with formula at night. I know the breast milk is so good for him but I feel like all I do is sit at my pump. Even with a hands free bra I can’t do anything with my son while pumping. If the only other reason I pump is to try to save money , should I just switch to all formula and save my sanity and time ?
