Almond milk in my diet making baby gassy?

My 5 month old, breastfed baby has had ongoing issues with gas and excess spit up. I eliminated dairy and she showed significant improvement. I switched to almond milk and spit up had decreased but gas seems a lot worse. Thought it was the arugula I was having with lunch and eliminated that after realizing it's a cruciferous vegetable and could be causing this, but gas is still horrible even after stopping for almost a week.

Has anyone ever heard of almond milk making baby gassy? I'm gonna try stopping almond milk for a few days to see if she improves, but curious if anyone else has experienced this.
