My niece had horrible gas, the gas drops werent workung for her either, so the doctor suggested special bottles that help reduce the air that she was intaking when she drank her milk,& she barely has any gas now. they're called Dr.Brown.
Dont know if you've tried this already but thats the only thing i can suggest.
Are you using gas drops or gripe water?
Also u can use soft pepermints! Just desolve one in a little warm water and let him drink it! Just go slow with it cause water it is so thin! I had to do it with my daughter, she had BAD gas from having to put her on formula! The peppermints worked! Good luck
Dr. browns bottles look them up.
Do u know what is asafoetida ??? U can buy from any Indian grocery store. Just make a pastein about a teaspoon of water n apply it all round the belly button . It's very safe n effective. He will pass all gas naturally n sleep peacefully. Do this once a day.
Thank yall so much! I havent heard of those bottles before and the drops not the water
