Is his tummy hard? If so gas can be very painful. With my kids we did the running (one knee two the tummy area and back down then the other knee) Touch your nose with your toes (both feet to the nose) Back rubs are nice too... If all else fails... And the tummy is still hard as a rock. Take his tempature- this causes muscles to contract and the child passes gas. But, watch out for flying poop. Make sure that you put a little vaseline on the thermometer and just like taking a tempeture but, with a little presure down (not in/ down) This may even cause him to go to the bathroom maybe with a stool harder than normal. Be prepared with a spare diaper and wet wipes. At six mo. foods are changeing and well, muscles are developing not as fast. Which causes the digestive system to run slow and produce gas. If it continues.. Is he on juices yet? if yes or when he does gerber should have prune juice. But, the thermometer save me from alot of sleepless nights. You just never know what is going to up-set tummies.
About me- Kids are 17 and 13 both are normal teens. No bathroom problems other than now they smell and think it really fun to make noises. I really don't think their is any connection. Most boys think it's a game.
Good luck... if you have any question write me. Also, I know that Rhonda H is a nurse you can ask her also.
