My DS has Chronic reflux. If breast refusal is the only problem it is unlikely to be reflux. Have you changed anything in your diet this may affect you milk.

My DS only slept in short spurts and always woke up screaming. We raised the head end of his cot. He would vomit almost all of his feeds and had very low weight gain. He ended up on on high doses of medication and now at 18months still vomits and is looking like having to have surgery to find the cause of the problem.
Sorry I cant give you any help because only medication helped to ease my DS reflux. Even now without the medication he vomits everything he eats and drinks.
