Switching formula super gassy baby

So my son is a month old. He is very gassy...like screams when he cant pass gas or poop. We burp him every ounce but nothing is helping.

My ped told me to use the gerber soothes probiotic drops...they are not helping at all. He told me not to use the gas drops because he's so young.

We have always used similac sensitive. I was thinking about switching to enfamil gentlease. Anyone have any luck with thus? Yes I have asked his dr about it..they told me to just keep using the sensitive kind..but i feel like they arent listening to me when i tell them about his issues.
