Kristen Bell and Dax Shepard Dropping Off Lincoln at School Makes Us Scream, "Nerd Alert!"

"So sweet! Hope Lincoln has a great first year of school! I was a mess on my daughter's first day. And I'm a teacher but I try to avoid the kindergarten classrooms on the first day because I cry right along with the parents," wrote one mom. "Such a sap! It's a wonderful and exciting rite of passage."

Another woman chimed in, joking that while the photos are beyond sweet, she has a bottle of Champagne on ice for when her kiddos head back: "So precious. Mine go back in four days . . . celebratory champagne already chilling and mommy happy dance choreography already locked in."
