Baby and gas

I don't know what to do to help.

I've done the basic patting and rubbing the back, putting him on his front and patting, bouncing, swinging, bicycle, crunches.

He passes gas... But he is still very irritable. He doesn't cry unless he is hungry or wants some comfort.

But I can hear his tummy gurgling and I'm getting upset like I'm doing something wrong.

He is 6 weeks and he is breastfed.

Otherwise he is a very happy boy...

Any suggestions?
