Any advice

I'm having a hard time. I exclusively breastfeed but I'm kind of wanting to switch to formula. I love breastfeeding but it's so demanding for me to be the only one to feed him. Yes I know I can pump so others can feed him but he doesn't allow me any chance to pump. Hes wanting to eat and the second I put him down he fusses until I have him again. He's 6 weeks. I just feel so emotional about it. He loves the boobies so I don't want to completely quit. I want to be able to pump and night nurse. I worry he will feel rejected or something. Anyone else feel like this?
