I’m going to add another psychological reason why I think the newborn phase is so particular... and the theory lasts through childhood too.
As adult women in this modern age, we get quite a bit of comfort and security from controlling aspects of our time and week.
It’s like we have our lives sorted into different pots on a stovetop. We can control how high we have the flame on under each pot, but they all have to stay cooking. So the pots might represent Work, Family, Relationship, Health, Social Life, Spiritual Life (church, hobby, volunteering, etc). We can pat ourselves on the back when we get the mix right in any given week, and get a bit overwhelmed and stressed if it goes wonky.
We have loads of info and advice from our culture about how to coordinate these pots. We know, for instance, that we need to exercise 3 times a week (or whatever), so we turn the gas up on that pot. Work has a set number of hours, so we can predict turning the energy up on that. We get practiced, and better at it. It makes us feel accomplished and sane. Our culture applauds us.
Then we add a leetle teeny saucepan marked Baby. Which somehow causes the gas to switch off under all other pots, to start with. And it multiplies to fill all the other burners. Ok, we say to ourselves, we can handle this, we’re used to lots of pots, we’ll crack the recipe and all will be well.
Truth is: you never have time to get things sorted, because as soon as you find a formula that works, the baby changes. It’s the baby’s job to change. Every day, in many ways. You can never get on top of it, you’re always researching, hoping, experimenting, pulling your hair out. There is no predictability to work with, or to take your satisfaction from. All you can count on is change. Is it working well today? That’ll change. Is it going badly? That’ll change too. Maybe worse, maybe better, but different for sure.
All our ‘modern woman’ tools for coping with chaos are no use in this new environment. It’s a new high-wire act every day, and that messes with our sanity. To go back to the cooking analogy, the smoke alarm goes off during the birth and it never seems to switch off!
It really is quite astounding that we manage so well!
