As some have mentioned here, (presumably) not knowing you’re going to have a baby can mess up the nuturing, bonding process.
This is because what…? Lack of anticipation, incorrect mindset, shock? I guess the question is what specifically is there in knowing that a baby is coming that turns on the nuturing machine. In other words (I guess I’m asking this of women who have had children). If you just woke up one morning (not anticipating childbirth) and there was the baby ready to pop would it seem like an intrusive stranger if you didn’t know it was coming? I can’t really seem to phrase this question right but hopefully you get the idea. A similar question might be interesting for people who were anticipating adopting a baby.
