The entitlement of bringing kids to a wedding they're not invited to astounds me. Weddings cost so much damn money!! I don't agree with bringing kids to anything if they aren't invited obviously, but bringing your kid to a wedding that likely cost absolute thousands and took months to plan is insane.
The Op of the post also commented later on that they found out because this woman sent a video of her kids saying how excited they were for the weekend which imo, is worse (and manipulative af!) because when you inevitably say 'kids are not invited', you're the one breaking the kids hearts because they were excited to come along.People have some obsession that their kids are loved by other people and an extension of themselves.
Unless you are specifically invited you don’t go, no exception for kids. If I was the bride I would be fuming.
