Bottle teats

Hi all, May I ask which teats do you think I should get for my newborn? Should I get 1m+ and 3m+? She’s coming in mid-Oct. Really need some advices regarding bottle teats. I would want to give her sufficient BM (latch or expressed). So not sure if these are the right teats? I bought Dr Brown’s anti-colic bottles as well as I’m afraid she might have colic.
