Excessive Wind In Older Babies Excessive Baby Wind Both Ends!?

Excessive baby wind both ends!? - excessive wind in older babies

My son is 6 weeks and is suffering at both ends to beat the wind. I've tried everything, what infacol bottle of Dr. Brown, etc. and nothing seems to work colief. I changed his formula and twice (I know that she could stomach, but honestly, I could not be worse). I only have him on SMA formula of lactose? He does not sleep because he wakes up every half hour and you get more wind. Screams when the wind goes, I went to the doctor and he told me that some babies are windier than others, but I am sure that his wind was not right - it seems that adults wind! Suggestions? Please help!
