OH YES!!!
My TJ is a BIG BURPER. He burps loud all the time! Usually after he eats...
BUT also at night, when we get in bed, he has a ritual. He sticks his nose in the blankets or under a pillow and he will snort and sniff really loud for a good 2 to 3 mins. Then about 15 seconds later, BURP. I swear, he does this ritual because he knows it will make him burp really good and then he is ready for bed
