Help! My husband has the most AWFUL farts in the middle of the night that wake me up from a dead sleep because they stink so bad. I make him go in the other room but I hate that!

Our little 9 month old sleeps with us and I’m pregnant which makes it worse because I can’t hardly sleep anyways. I have to shake out the covers because they stink so bad and I can’t breathe. So it wakes both of us up and sometimes our 9 month old and literally they will stink up the whole room. His mom has said when he was in high school the moms in the car pool would literally stop at gas stations to get gasX because they stunk so bad. And that he would have to marry someone patient to deal with the stink🤪 Any suggestions??? I hate that I wake up to every single one of them! It keeps me up! Idk what to do besides make him sleep in another room
