New to this group and have a question!

Our baby boy is coming any day now (EDD 4/1) and I am so excited to breastfeed! I am currently deciding if I will return to work or not, and thinking about pumping is very stressful. I really wanted to exclusively breastfeed (no bottles) for as long as possible. It makes me sad to think I would have to start using bottles when he is 4 months old. I would only be working four hours a day. Is it possible to do boob and bottles, or does it just depend on the baby? Is there benefit to exclusively feeding from the breast or is breast milk from a bottle enough?
