Let's say you had 40 servings of BM in the freezer and formula has been introduced without any problems. The baby is almost at the 1 year mark and you are ready to wean at that point.
If the baby takes 4 bottles/day would it be better to give 1 bottle of BM and 3 bottles of formula each day for 40 days
or to give 4 bottles of BM for 10 days and the remaining 30 days do 4 servings of formula?
Is there a nutritional benefit either way?
