Everything is of utmost importance to a toddler. Each experience must never end. Sharing is a monstrosity invented by cruel parents to torment and disgust. Fun places are not even fun because they know that eventually the fun will end. And that knowledge is enough for them to start crying about it before we even get there.
The energy it must take to be a toddler, I can’t even imagine. They have so many *~feelings~*. How can they even survive with all of these tortures in place to tease and torment them? Adult distraction doesn’t work anymore, they’re too stubborn for that. Reverse psychology? They learned that game six months ago. Nothing doing. They are going to cry and they are going to cry now and there is nothing anyone can do to stop it because the world is just too much.
But, when our adult tactics fail our children often enough, they adapt. They move to their own solution, often one that we would never have thought of.
