Need advice for my gassy baby

Im a first time mom and my little man is 3 weeks old. Since my milk came in, I’ve noticed he’s having a lot of trouble passing gas/pooping. He groans and grunts and he’ll even cry out in pain. 😢 he’s miserable most of the time and it makes sleeping difficult for both of us.

I’ve tried gas drops, gripe water, burping during feedings, bicycling his legs, warm baths and I cut caffeine out of my diet. Nothing seems to help

. Anyone else have this problem with their baby? Is it something he will grow out of?

I’ve heard probiotics can help, but I don’t know what brand to try. I also heard cutting dairy out of my diet could help too.

Any recommendations or suggestions would be greatly appreciated! I hate that I can’t help him feel better.
