Baby waking up due to wind

Hi everyone! All advice would be really appreciated.

My 3.5 month old exclusively breast fed baby boy will wake up 3 times between midnight and 6am crying and pushing to get his farts out. Only when I help him with exercises and / or a windi do the farts pass, then I breastfeed him and he can sleep again. He can’t self soothe to sleep and I’ve tried pacifiers but only the boob will help him sleep.

He has no problem passing gas and poos during the day and he doesn’t like formula.

Can someone please recommend me something which they KNOW works / worked for their baby? I’ve tried so many things.

Thank you!
