Gas due to foods I’m eating?

I generally avoid dairy because it makes my tummy upset but I’ve been consuming it again lately coz I wanted to - I’ve noticed the last couple of days my poor Bub has been really gassy during breastfeeding and pulling off the boob to burp every 2m or so - could there be a link between my dairy consumption and her gas?

I’m gonna avoid dairy for the next week to see but has anyone else had this happen?

Could it be anything else I’m doing?
