Bottle feeding help!!

My son (8 weeks old) has just been diagnosed with cows milk allergy and reflux, we’ve been given special formula for him so he isn’t sick and screaming all day and night... he uses my nipple not only for feeding but also as comfort if he wakes up briefly from a nap. He has eaten literally 8oz of formula for the first time ever and now is still trying to get to my breast an hour later what the hell do I do, he only wants my breast and a bottle won’t satisfy him at all?!?
