Newborn milk bottle

I bought the Avent 125ml but stopped using after 2 months coz baby’s intake was more than 120ml. The Pigeon 160ml ones are good, can last pretty Long if you feed baby BM. If it’s BM, usually the intake won’t be more than 160ml as the caloric intake of the BM changes as baby grows. But if it’s FM, you would definitely need a bigger 240ml bottle as baby’s intake will increase to past 160ml (the content of FM can’t change to suit baby’s needs, hence the amount has to increase sufficiently).
