Re after the newborn period: Peter Hartmann's team (and others before
him) has demonstrated that babies, at least those between 1 and 6
months, being exclusively breastfed, do *not* increase their intake
significantly at all as they grow bigger, which blows all
calculations of intake based on their weight out of the water! The
amounts in the first few days are tiny (only a few mls of colostrum
on the first day) and climb rapidly to the 'plateau' after the milk
comes in, so I am not sure if a mathematical formula using weight
would ever be correct??
The amounts in Peter's studies were consistent for an individual baby
but were *very* variable between babies - from less than 500 ml per
24 hours to over a litre. There was no way of telling from casual
observations which babies were taking a lot and which took less. All
were happy, thriving babies.
I understand that there are mathematical calculations for
artificially-fed babies, and we used to use one of these for
breastfed babies, as we had no other way of estimating this. We used
to use 150 ml/kg/day, I think it was. We stopped using this a few
years ago, once Peter's data were revealed. I now also wonder how
physiological this calculation is even for artificially-fed babies.
If they are as variable as breastfed babies, it will be OK for some,
insufficient for others and too much for yet others.
So it is much harder to tell a mother who is expressing what amount
her baby needs per day. She needs to discover this for herself more
by trial and error than anything else. This makes sense to me -
adults all don't eat the same amount according to their body weight -
why should babies?
