As regards to how much your baby should be having each day we
use a basic sum which will help you calculate how much your baby needs per day:
So up to the first 6 months of life your baby should need 2.5
ounces of formula for every pound of their body weight.
Firstly we take your babies weight as a guide. So for example
say your son is 8lb, so we know that we would need to times 2.5 ounces of formula
by your babies weight, which is 8lb to get how much they will need per day
The sum would be 2.5 x 8 = 20
The resulting figure (20) can then be divided by the number
of feeds they are currently tolerating. So say for example your baby is having
5 feeds a day you then divide this figure by the ounces needed per day (20)
and this will give you the number of ounces your baby should have at each feed.
20 divided by 5 = 4 ounces of formula at each feed.
