I'm joining late
Just read (actually listened to) the whole book...
One thing that I've been thinking about is how other people's perceptions of me have made me doubt myself. For example, DS is 2 1/2 and has never been left with a babysitter. We are even cautious about leaving him with family (and we have our reasons for that specifically). But when people find out he's never been left with someone, you should see the looks I get! Like I am a freak! Yet I am just listening to my instinct, and I am a SAHM so we really have no need for someone else to watch him. But I've found that I'm almost embarassed at times when it comes up, because people think I am overprotective.
I think this book really helped reinforce to me that it doesn't matter what society tells me - I need to listen to my instinct above all else.
