Wheat intolerance?

My daughter is now 12 weeks and has always struggled with excessive gas. Whenever she gets wind she will cry for hours before passing it and like she’s in pain with cramping.

My doctor suggested cutting out dairy which I did for a month with no change. Since then she has had some bad times and I started to link it to cheese particularly.

Today she’s having a particularly bad episode. Last night I had pizza for dinner and I thought it could have been the cheese until it just struck me it could have been the base. With hindsight when I’ve previously had cheese it’s been with pasta or bread so perhaps it’s the wheat?

I will now try cutting it out but has anyone else had any experience of this with their little ones?
