i think option 2 is the best
i think i read somewhere that it is best to introduce formula (or a change of formula) for 3 days..
day 1 - 4 meals concentrate + 1 meal powder
day 2 - 3 meals concentration + 2 meals powder
etc etc
until all meals are replaced with powdered formula
that way you can observe any changes in your baby during the 3-4 days in case of allergies and/or other digestive reactions (constipation ..etc) |
