Sleeping beauties

Tonight, we cuddled in Kyla's bed and read books as Greg got called into work. Both kids insisted that they needed a slumber party and wanted to sleep together. Typically, I would answer with a simple "no" and take Nolan upstairs after reading.
But... what's the harm? It's a Friday night, it was fairly early, and why not let them do something special?
I can't believe they actually fell asleep in a timely manner. It was so cute!
