Gas issues

Gordon
Aloha,
    We are having an issue with our son, he Is two weeks old and has gas build up. At times his crying is simply because he is uncomfortable. We have tried the little remedies gas relief drops and switched from similac to enfamil "gentle ease" powder formula with no success. 
It has become an issue due to the long nights. It seems like once the sun goes down the issue starts to flare up. Any advice you or your partners would be willing to give would be greatly appreciated! 
-God bless
