Hi,
one thing my pediatrician told me a long time ago was that we must understand a baby's digestive system. First, it's brand new... it doesn't start functioning until birth. I noticed all of my babies have been affected with seemingly painful farting. sometimes it's hard not to laugh even though they are writhing in discomfort... it's kind of amusing sometimes to see them lift a leg (though not on purpose) and rip something so loud it rivals those of my gassiest guy friends!
That being said ther are a few things you can do to help them push the gas out. Mylicon never worked for my kids either... not sure why this is, but I've always used Little Tummies. My ped told me you can't overdose a baby on this, though I would still follow the bottle directions. I gave it to my kids before a meal, which sometimes was about every 3 hours.
make sure you are burping well and often... even between bottles. crying can make them swallow air and need a burp too. I lay the baby on my chest so my boob is kind of putting pressure on their tummy... it's firm but forgiving at the same time :) I also walk with the baby upright on my chest and make exaggerated up and down movements to kind of dislodge tiny air bubbles within the stomach. these things will help prevent gas. but once it's in the intestines, you have a whole other monster on your hands.
I will give baby a little tummy massage using very gentle pressure.. wakling fingertips from left side to right and back again, working my way down... and also take the babie's legs and make him do a bit of a pedal motion, it helps push the bubbles through his intestines and out his cute little tushy in the form of those adorable shameless baby farts :)
He should get better at this with a bit of time... his little body is just getting the hang of digesting food.
Hope that helps :) Congrats on your new little boy!
