Thank you hugemanatee, I certainly identified with it and this thread is making me feel like some sort of fucking mutant.
Look, I found the first days exhausting and crap. I remember nothing about them fondly..... for my first. For the second, I was emotionally prepared (because I'd, like, done it) and so actually enjoyed small parts of the first months. Overall I just bloody hated it though. Either I've had PND twice and been missed twice or my reaction is within the spectrum of normal.
And I did resent DS1 bitterly in the first weeks. I rationally knew he was helpless etc but that didn't make me like him. If anything it made me dislike him more for putting me under so much pressure (albeit unknowingly) to appear loving when really I just wanted to close the door and leave him to it. I didn't, but God I wanted to.
I much prefer my kids now - they are still constantly demanding but I get so much more from them now. Conversation, hugs, love. I felt none of that from or with my newborn. It took me months to start liking him.
