TJ has stink butt ALL THE TIME!!!
At night, in bed, before he settles in, he does his ritual:
Digging and Snorting and Sniffing under the Blankets.
After a few minutes of this behavior, he lets out a BIG BURP and FARTS a few times. Then he settles in to go to sleep. My hubby thinks that he does that sniffing and snorting on purpose, that he knows he has this built up gas and he wants to get it out fast and go to sleep.
