Breastfeeding second baby....

Is there any mommas that Breastfed your first babies but aren't sure about feeding the second. I feel incredibly selfish, but also I want to have time for my first daughter. I was so tired with my first I started hallucinating. My husband didn't get paternity leave as he had started a new job and we just couldn't afford to be both off. This time he'll get 2 weeks, so could help with bottles. I feel like I've only just got my boobs back too as I nursed my 1st until she was 2.5. She's now 3. Or anyone who has combi fed any advice 🤔
