I hadn't heard Jeff Cohen's 2012 radio interview with his daughters about the disastrous haircut the 5yo performed on the 3yo's head, but it's fantastic. I might even listen to it again right now. [3min later] YEP, still great!
And while I'm stoked that Cohen got a book deal out of it, and that Eva and Sadie and the Worst Haircut EVER! came out last year, and sounds like it captures the story so well, and even though Harper Collins Children's imprint has advertised on Daddy Types before, and I'm grateful, hoo boy.
The idea of reading a kid an endearing, engrossing story about a horrific haircut seems like an INCALCULABLY HUGE MISTAKE. How can it NOT be planting the seed for a haircut adventure? It might as well come packaged with two little sets of scissors!
Maybe keep this story for yourself, and back Cohen's podcast Kickstarter or something instead? Just thinking out loud here.
