I provide everything for the party (decorations, food, big gift) and the kids bring one gift
each for the birthday child. No names on gifts to prevent mom* shaming. $20 limit.
Families with multiple kids receive multiple gifts therefore are expected to contribute as such or simply not participate. As the host, I think it is rude to expect each of your kids to receive gifts on their birthdays but only bring gifts from one of them on others birthdays. Rude, selfish and entitled. Change my mind.
* I have never had dads shame one another for the price of kids birthday gifts. Forget entirely? Sure. But compare and keep score of the cost of gifts? Nope. That's a mom thing.
Nothing changed with the birthday party policies, here, for COVID. Kids have already lost enough.
