Has anyone read it? SOOOOOOOOOOO fascinating.
I cannot recommend it enough for parents and soon to be parents. My dad has been hounding me for six months to read it and I'm so glad I finally am. In fact he buys it for everyone who fits into the parents/stb parents category.
It's like Freakanomics for parenting. Which means I find myself nerdily talking about it to anyone who will listen, but I will spare you all and just encourage you to buy yourself a copy now now now.
