The cute factor is on overload in this new viral video. In it, a little girl is crying because she can't stand the idea of her adorable baby brother growing up.

She is overcome with emotion as she kisses him sweetly and hugs him between tears. "Oh you are so cute! I love your cute little smiles!" Watch for yourself.

This video is so endearing and captures the innocence of a big sister that will resonate with mothers everywhere. I can not tell you how many times I held my little babies, tears in my eyes because they smiled for the first time, crawled forward gingerly or stood with the help of my strong hands. As they grow up before my very eyes it's hard not to feel exactly like this little girl does.

My last just girl just graduated from preschool and the emotions were almost overwhelming. When she starts kindergarten in a few weeks, I will cry again.

It seems that motherhood, or sisterhood in this case, is harder than we anticipated. Aside from the day-to-day care, the lesson teaching and the discipline rituals, every day seems to hold a milestone or accomplishment that we have to accept. I am constantly looking at my girls and wondering where the time went.

We all know that sibling rivalry is on the horizon as the little girl and baby boy get older but, on this day, she encapsulated the words and tears we all feel when our little babies grow up too fast.
