Can you imagine having FIVE girls under one roof? The really good news is that there is probably always plenty of hairspray, cute sweaters and gossip. Remembering when I was the precious age of 10/11, I would have LOVED to have had an older sister, for advice, someone with knowledge (and coolness). 
Photographing sisters is always so MUCH fun, because girls this age LOVE having their picture taken. Or maybe it is just me... maybe I am suddenly super cool.
