I'm reading it right now and loving it! It's taking me forever to get through (not because it's a tough read or anything, life just gets in the way), but I'm really enjoying it. I like how she ties her experience in neurobiology back to AP and how mammals were made to parent this way.
She is also very respectful of other choices. DH and I are huge BBT fans, so I have a hard time not picturing her saying things in Amy Farrah Fowler's voice.
