Simply put, she just turned off their Wi-Fi and left him to sit there and stew.
The wife, who goes by the username FinalWintersEve shared her story on Reddit and asked her fellow users whether they thought she was being an 'a**hole' for truncating his toilet internet time.
Basically, while the couple were on maternity and paternity leave following the birth of their twins, she started to notice that he was spending a whole heap of time on the throne.
It was at about this point that she figured out that he'd been hiding in the bog in order to shirk his nappy changing duties.
So, she started flicking off the Wi-Fi router while he was in there watching YouTube in order to flush him out, so to speak.
Sharing her story, she wrote: "Anytime my husband SHOULD be doing something with the children ( it's his turn for a diaper, a bottle, even just soothing a fussy newborn) he ALWAYS goes to the bathroom first.
"My husband is on medication that makes him spend a lot of time in the bathroom about an hour after a meal. It's a medication he has been on and off several times over the past year.
"He is never on it for more than a few weeks, and it does not affect him all the time, but he always claims that is why he is in the bathroom."
She continued: "I would rather let him use the restroom first than have to put down a baby mid task, but over the past couple months he has been spending more and more time in there.
"He always takes his phone. He is always watching YouTube. His average session is 25 minutes in there, often longer, rarely shorter."
That's when she started to keep track of his toilet times.
She added: "Yesterday was a week and a half since I started truly keeping track, and he, only twice in 10 days, not ditched me to go camp out in the bathroom and let me finish 80 percent of the childcare.
"Today I started a new rule. If he is in the bathroom for more than 10 minutes, I flip the Wi-Fi off.
"He has not spend more than 15 minutes in the bathroom at a stretch today, but is extremely upset.
"I feel like the fact that without the Wi-Fi his uncontrollable toilet issue cleared up rather quickly proves why it needs to be done, but he feels I am being unreasonable, and I need to make sure sleep deprivation isn't making me an a**hole."
Broadly, it seems as if people agree with her. In fact, most people are of the opinion that her husband is, in actual fact, the a**hole for allowing her to bear the brunt of the childcare.
Come on, mate. Get off the toilet and do some parenting...
