When you are strictly breastfeeding, figuring out whether your baby's getting the right amount to eat usually comes down to a pretty simple calculation — if enough is coming out in the diaper, then there is enough going in.
With bottle-feeding, however, this is not always as clear and simple.

If you find the ingredients in American formula less than acceptable and order European baby formula due to the pure, clean organic nutrition then you will need to take into account time for shipping and delivery.
This is when rough guidelines for baby formula amounts can make all the difference.
