Rookie FTM question
I feel so silly asking this (seems like it should be self explanatory) so please don’t judge me 😅
I know adding the formula powder to the bottle adds more volume. If I make a 4oz bottle and the 2 scoops of power adds volume to make the bottle 4.5oz am I still giving baby a 4 oz bottle or is it technically now counted as a 4.5oz bottle?
