My 4-year-old misbehaved at a wedding — the bride had a meltdown and threatened to call security

Bridezilla, meet the littlest monster.

Two best friends suffered a rift after one accused the other’s 4-year-old of ruining her wedding — all over an ill-timed cake-eating incident that nearly wound up involving venue security.

The reprimanded parent recently took to Reddit in a later-deleted post to share her side of the nuptial nastiness — and to ask whether she did the right thing by “not apologizing,” according to The Independent .

The peeved poster shared that the bride had already been on the fence about having kids at her wedding — for fear of them “messing things up” according to the beleaguered BFF. She was reportedly ultimately swayed by the input of close friends who happen to be parents.

Things started off well, the woman claimed, writing that “I brought quiet activities to keep them entertained and everybody behaved. I even cried because of how lovely it was.”

“The kids were running around and playing with each other and it was a fairly secure space and I knew almost everybody there, so I felt comfortable with my son playing with the other kids while my husband and I had fun dancing,” she wrote.

But when it was time to cut the cake, everything went horribly wrong — the precocious preschooler made a bee-line for the sugary centerpiece and began helping himself.

“My husband and I push forward to see what’s wrong. I see my son with frosting around his mouth and on his fingers,” she penned.

Admittedly, the woman said, she and her husband “were a little slow getting there” to chaperone the baked good-loving brat — triggering a massive, very public outburst from the bride.

“The cake had a small chunk taken out of it. I try to apologize but my best friend turns around and yells, ‘This is YOUR FAULT. Your son RUINED my cake.”

The bride’s guilt trip apparently didn’t succeed — soon, the two were shouting at each other.

“He’s only here because YOU told me it would be worth it to include the kids!’ I yelled back, telling her that it was just an accident and the rest of the cake was still edible.”

Things escalated even further, with the bride said to have loudly evicted her friend from the venue — even threatening to get security if she and her offending offspring didn’t leave.

The bride’s sister later reached out and “apologized” for how things went down, according to the original account — too late, the poster insisted.

“I think sorries are out the window now after her outburst. I told her sister so and said I expected an apology first before I’d say anything to her,” she wrote. “Not only did she blow up at me in front of everyone, but at my son. I’m humiliated but even more angry on his behalf.”

Despite the bride’s over-the-top reaction, Redditors were quick to give the mom a scornful parenting lesson.

“Your child is very young and in need of supervision. It doesn’t matter how secure the location is, there are a lot of things that are NOT secure (like cake, glasses, etc) in the venue. Not only should you apologize, you should have apologized right then,” one person commented in the still-live comment thread.

“YOU and your negligent parenting are the reason people don’t allow kids at weddings. You ruin it for parents who understand that littles need supervision and would be with their kid making sure they behave, and removing them if they don’t,” added another.

“I’m so sick of parents thinking just because they go to a wedding, a family party etc that it means they can just relax and not parent for a bit,” a third replied.
