It can literally happen in the blink of an eye. It certainly did today, countless times. In one moment, a joyous and bubbly giggle fills the air of my forever home. In the next, one of the world’s happiest sounds is replaced by a soul-crushing scream of anguish.
I do find it happening a bit more frequently lately, with all the teething going on around here. I think that’s what led to the roller coaster of emotions I witnessed today, with the tears and the giggles somehow creating a symphony of emotional reality. 
As dear baby Carter approached bed time, a time when he should have been pretty tired after not napping at all today, he exuded energy. And as I watched him run through the house with his bare legs hanging out (because his pants had already gotten changed twice, and it was warm enough for such silliness again today), squealing with joy, I couldn’t help it. Somehow that moment seemed to erase all the other not so happy ones scattered randomly throughout the day from my mind.
I realized, as the squeals evolved into more of a squeal/laugh combination, that is the magic of this emotional dichotomy. We all experience it in our daily life, but time has a way of training us to keep it inside. Time has yet to do that to Carter, who literally wears his heart on his (usually blueberry-stained) sleeve. So he laughs and cries and questions and thinks and laughs and cries some more (all in the span of 30 seconds) in a very public way.
Though it pains me to experience sometimes, I’m thankful to frequently bear witness to the emotional roller coaster ride of toddlerhood. Because it can literally happen in the blink of an eye. Laughter can become tears that quickly.
But, even better, tears can become laughter that quickly. And that’s life. Things have a way of happening that can sometimes take us by surprise. They can rock the emotional boat enough to completely change the tide. Taking control of the boat and immediately turning it back the right way? That’s a life worth living.
