We found that with DS that most of his problems came from wind. If he didn't have every tiny bubble burped up, he'd cry. Our saviour was Infacol. We'd give him that before each feed and he'd burp up a storm. Problem solved.

The other thing I would suggest is maybe reflux? If he sleeps when he's upright, it may be because it keeps the acid down? Might be worth investigating?
