Foods to Help Lessen Gas?

My LO is a month old and efb. He has been gassy from day one - meaning he 💨

I have no idea what’s in my diet that makes him fart like his dad and oh god they smell too. No biggie really. Just wondering if there’s any foods that other people have had a big problem with them making their baby fart like crazy.

He doesn’t poop a lot also. The pediatrician said it’s fine as long as it’s not hard when he does poop and it’s every few days.

I’d really like to make sure I eat good foods for him to help his belly. Thanks for any tips!
