Two little blond kid boys playing together board game at home. Funny siblings having fun. Twins and best friends, toddlers learning interact, win and lose.

Kids love getting mail. It’s one of the reasons subscription boxes are such a hit with children who are used to seeing the grown-ups claim all the letters and packages. They get their very own box of stuff! But what happens when you’ve got more than one child? Subscribing to a box for one child can end up making a sibling feel left out.

That’s why we’ve pulled together the very best kids subscription boxes for siblings! From boxes that include discounts for adding on an extra child (or more), to boxes that contain projects and activities that kids can do together, get ready to put sibling rivalry to bed… well, at least so long as they’ve got their box in front of them. (Hey, we’re not miracle workers!)
