chrys,
i share tis wif u then u know how much ur bb will drink n wat kinda bottles u need ok? hits 2 birds wif one stone.
in ur bb's 1st mth, he'll b drinking abt average 60-90ml (can be lesser, can be more)
2nd mth, average 90-120ml (can be lesser, can be more)
3rd mth & beyond, above 120ml (can be lesser, can be more)
bbs drink every 2hrs in their 1st 4-6wks. after tat, they can drink every 2.5-3hrs. only by 4-5th mth, they can then stretch 2 every 3-4hrs. not ALL bbs follow tis guidelines. some bbs can still b drinking every 2hrs when they r abt 2mths old.
wif such a drinking pattern & volume, 4x4oz bottles are enuff. i only used 2 bottles last time cos i was also feeding my son EBM in the glass bottles. i expressed BM, stored in glass bottles n warmed up e EBM, put the teat on (the nuk/pigeon teat holders fit glass bottle), feed directly.
