Breast feeding help

I don’t know if I should be annoyed or happy

My family is trying to get me to switch to formula and I really don’t want to they think her feeding ever hour during the day is not normal,

- I was only feeding her on one boob each feeding just switching each time she’s 3 weeks old a friend told me she should eat on both each feeding so I started that today.

- she falls asleep when eating so I just figured she was done eating ! But clearly that’s not the case cause if she wakes up when burping she wants more so I feed her.

- when do I know my baby is done eating?

- how long should I feed on each side!?

- why does she get the hiccups? How do I prevent them?

- when should I pump? To insure I’m producing enough?

Thanks for the help
