Ive been trying tonswotch to formula for a month now woth no success

Megan

My baby refuses anything that isnt breast milk. He even knows when i put a dash of cereal in the breastmilk bottle.Hes denied 6 types of formula ive tried ever since he was born. My next idea is to starve him till he gets hungry enough to take formula which i heard could take up to 2 days. Im running out of ideas and the baby only sleeps for 6 hours a night and nada during the day for the past 7 months . Me and my husbund are crying for change.
