He is growing...

Today I could hear giggles over the monitor. I walked slowly into his room, as to not disturb whatever it was that he was finding so fun. I found this... 

And in that single instant I realized just how much he was growing...and my heart grew full and heavy at the same time. Simultaneously bursting with joy and breaking with the ache of the knowledge that my time with him, just as he is now, is short lived. He will grow, he will change, the nature of our relationship will change...his laugh will change, his hugs will change...but I will always remember him like this.
