Switching to formula!

Rachel

I have been successful in eliminating the day time feedings and replacing them with bottles but the feed before going down for bed and the overnight feed she has just freaked out when trying to give a bottle. The overnight feeding she will take the bottle eventually but will not go to sleep unless given the breast, it I am starting to dry up so this will not be an option anymore soon! Anyone else go through this they can give me some advice??
