Amount of milk to feed for new born

If you look at the formula tin, the amount pee feed depends on the number of feeds per day. For each feed, I calculate by: the baby's weight x 150ml ÷ number of feeds. Baby's weight x 150ml is the least your baby needs per day. I asked my pd, and he said the calculation can be up to maximum of 210ml. First week for my baby at 3.1kg was: 3.1 × 150 ÷ 8 = 58ml So she was drinking at least 60ml every 3 hourly. She drank more frequently on certain days, but it was fine as long total per day was under 650ml (3.1 x 210).
