Bottles for air intake

I’ve religiously used dr Browns options+ & Phillips avent anti colic. Neither of these have helped with how much gas my LO has. He cries out and then passes gas and will be okay for s bit. Except for today he has been miserable all day long.

Someone with experience in bottles or similar situations please give me your advice!

He is also on Nutramigen and his stools are soft but also has a bit of s tough time passing stool but eventually will get it out.
