Size of feeding bottle for newborn

I didn’t use newborn bottle, it will be a waste. I bought 150ml , n used newborn teat. ( can use S, M, L, XL teat) & standby 240ml. My friends are using Hegen bottle. They said it’s good! Up to 6 months, got to change. If you feel is expensive for Hegen, alternative anti colic bottles. Tommee tippee/Avent/Dr brown. Dr brown ( washing part is quite troublesome) some mummies ok , some mummies not:) I find autumnz are quite affordable, u can get it from Q10. (BPA free and Phthalates Free) U can use for milk storage also.

I use Hegen 150ml till 3months and switch to 240ml Personally I like it cause it's easy to clean, i use 150ml bottle as BM storage as well
