My son has been BF since birth and is a very happy BFer. He will now (after much perseverance) take bottles during the day and be BF morning and night only but only takes the bottle if the bottle contains breastmilk and not formula. He will sometimes take a 50/50 mix if in the mood. Not a problem now while I can express during the day but wont be able to when I go back to work due to nature of my job. Has anyone got any top tips to get a baby to accept formula? Any suggestions at all would be much appreciated as dont want my little one to starve during the day!
