Parent Dragged for Saying Sister-in-Law Was 'Wrong' To Change Baby's Diaper

A parent has been slammed online after she overreacted to her sister-in-law changing her daughter's diaper while she took a work call.

In a viral post on the U.K.-based Mumsnet discussion website, user CHun25 shared a story that has attracted more than 445 responses since it was posted on June 18.

In the post, titled "To think SIL (sister-in-law) was wrong to change my DD (dear daughter)," the parent explained: "Not sure if I am overreacting but I would like to hear others' opinions. We went to the park yesterday with SIL and her two kids.

"It was a nice hot day and we were having a great time. I had to take a work call so SIL kept an eye on DD for 10 minutes.

"As I get back I see her putting DD's trousers back on and she's rolling up her nappy. I just thought it was a bit peculiar that she didn't ask me or anything.

"I would never dream of doing that unless she asked me to or she was gone for a while. Am I being unreasonable?"

The parent later added the baby had not soiled the diaper but had instead peed, leaving it "wet but not full."

According to the U.K.'s National Health Service (NHS), changing a diaper as soon as possible could prevent a rash from developing on the baby's skin.

It added: "Young babies may need changing as many as 10 or 12 times a day, while older babies need to be changed around six to eight times."

The sister-in-law's sense of urgency was not lost on the dozens of commentators who praised her for changing the child's diaper.

One Mumsnet user said: "YABU (you are being unreasonable). Your SIL is lovely. I hate changing nappies and would have left your DD wet or dirty until you came back so you could deal with a squalling child and stinky mess by yourself.

"I think you should have thanked your SIL because I assume your DD is too young to do so herself."

Another added: "I doubt she was changing it because she just loves changing nappies, so she was just clearly trying to help out."

A third posted: "YABU, why would you want someone who cares for your child leaving her uncomfortable?"

According to the NHS, babies have very delicate skin so their diaper "needs to be changed as soon as they wet or poo themselves, otherwise, their skin becomes sore and red."
