If you’re a parent, you'll understand how important it is to change the nappy of a baby once they’re crying and it smells…unpleasant.
But, would you change a nappy on your friend’s floor without asking first?
That’s what one woman is said to have done, bringing out her baby changing mats and fresh nappies without asking her friend’s permission.
In a post that's recently resurfaced online, the mum's friend took to Netmums to complain about what she’d done, putting a disclaimer that she isn’t a parent herself so might be more sensitive to this sort of behaviour than other parents.
"Mid-pleasant catch-up it's apparent 19-month-old needs nappy changing and it's definitely solids," the anonymous user shared on Netmums.
"Friend proceeds not to break conversation but whip out a very small changing mat and some wipes, etc., lay it all on the carpet and introduce fresh fecal matter into my front room."

She explained that she was confused at first as to what was happening and tried not to be disgusted but her digestive system now has an "overpowering scent of poo accompanying it."
"I am very supportive of breastfeeding in public, etc., that just hasn't got any argument against it, why should anyone be made to eat their lunch in a toilet," she wrote. "But in the same vein - why is it acceptable to change a nappy in a living room rather than a perfectly well-equipped bathroom or even ANY other room that we are not drinking tea in?"
The woman said that she’s not usually squeamish, but found what her friend did rude.
"I get that you are probably completely immune to your own child's effluence, but to expect others to find it as delightful seems unreasonable," she wrote.
This has sparked a ‘nappygate’ debate on the thread, discussing what was the correct etiquette for changing a nappy at a friend’s house.
"I don't think it's particularly nice to have someone change a smelly nappy in the same room as you're sitting having a drink/eating (even if they are happy to do it at home, that's their own choice!)," another person wrote. "The smell does have a tendency of lingering so it's only polite to ask if there's somewhere else it can be done."
"Changing nappies is just something that you do without even thinking about," one user pointed out, defending the woman.
"Whilst it's not something I would do at a friend's house, I do think you need to get a grip. You are still so upset hours later that you have decided to write a very long rambly rant about it," another person commented. "It's a baby's bum being changed, is it really that offensive?"
"In someone else's house, especially someone who doesn't have young children, who I haven't seen for a while, I would definitely ask where to change her nappy," one user added. "It's just common courtesy."
"OK I'm the rude friend that just changes my baby's bum," one mom admitted. "I never thought about it being 'offensive' to anyone, I mean would you want to sit in your own sh*t for longer than necessary?"
