How much breastmilk should I put in my 2 week newborns bottle?
There is a great calculator for estimating the amount of breastmilk baby would need here: http://kellymom.com/bf/pumpingmoms/pumping/milkcalc/
"Estimate the number of times that baby nurses per day (24 hours).
Then divide 25 oz by the number of nursings.
This gives you a “ballpark” figure for the amount of expressed milk your exclusively breastfed baby will need at one feeding."
