Best gas drops stat!!

My baby has had gas issues since day 1. I’ve been using Little Remedies gas drops but I feel like I need to break out the big guns. He is breastfed and he gulps air while nursing, he cries a lot so he also gulps air then, and he also has the hiccups ALL the time. I burp him plenty but he just takes in so much air. What can i do to help him!? He has the biggest toots I’ve ever heard and he seems like he’s in pain ☹️ Also, what can I cut from my diet besides dairy that might help?
