have you tried gripe water for the wind? it's got fennel in it which should help calm his tummy, either that or a fennel tea for babies I'm not sure where in UK you can get it but it's quite common over here and it's basically the same stuff that's in gripe water but you give it as an additional drink.
or ummm Tyler was really windy and we just had to distract him enough so that he relaxed and then the wind came out... Finlay is a bit windy too but not as bad we just keep shifting his position and that seems to help.
