You poor thing, I'd say I remember it well, but really I just get flashbacks. I remember being asked what it was like at the time and comparing it to being in a war
. But no, it is horrible. There's a reason why torturers use sleep deprivation. I'm keen to have a second child but I keep remembering the horror of the first few weeks... and then I look at DS running round the room like a loon, or "reading" a book, and it IS all worth it - in the long term. The short term is unbearable. I shoved DS into DH's arms and got out of thebedroom one night because I felt like I wasn't going to be able to control myself from slapping him, and I would never, ever raise a hand to anyone, let alone a defenceless baby. So I know exactly what you mean.
A couple of thoughts that I used as mantras were:
This is temporary. It will pass.
This isn't personal. My son does not hate me, it's just that his hunger alarm has gone off.
The buck stops here. I have to do this. I am the Mum.now (oh shit!).
I'd add my voice to those recommending expressing, and also that, unless your other half works as a brain surgeon or air traffic controller, then he should be helping. You cannot keep going without sleep. Oh, and if he ever says, "Okay, I'll take him if you can't cope", we'll send the lads round for a word. My DH was okay but only about 75% as useful as I'd have liked, and much worse than me about getting up in the night. Time for your OH to step up and be a man.
The other thing that saved me, oddly, was getting out of the house at least once a day. I need fresh air and get depressed if I'm indoors, being tortured by a mad baby who won't let me sleep, day after day. Get out, see the sky, talk to random people in the park when they admire your lovely son.
You can do it. If I can, you can.
