FTM- does caffeine cause your BF baby's gas??

Still trying to figure out my 6 wo EBF LO's gassiness. It's pretty much every day, at different times of day, I haven't noticed a difference with the foods I eat. I had an epiphany tonight- I drink 1-2 cups of coffee every day. Could this be why?? She's gassy from intestinal gas (lots of leg crunches and big toots/diaper explosions) so I know it's usually not from swallowed air because she doesn't always burp during or even after a feed. What is your experience with your baby? I didn't drink coffee when I was pregnant. I was considering gas drops but I want to try to fix my diet first so that I don't have to medicate her daily if I don't have to! TIA!!
