I agree with everything that has already been said. TBH I'm stunned they showed you a 'day in the life of a fretful baby' type thing - every single child is different, chances are you will have no routine at all at the beginning and every day is different.
I know it's a cliche but seriously, millions of couples have done this and gone on to have more little ones, do it can't be THAT bad can it?
We were lucky and I just slept and ate for the first 6 weeks. However, she was still up lots in the night. We lowered our expectations, ate easy meals, accepted help (I wish we'd accepted more though!) and just went with the flow. It's a big change but you adjust and adapt. Little ones need lots of sleep and there is nothing to say you need to be up and dressed if they wake for a feed at 6am. We used to do that feed and then all to back to bed some days. There's also nothing stopping you sleeping in the middle of the day.
You just do what you need to and what feels right to get through. I remember walking up and down the living room for hours with the swinging chair music playing, bouncing I. At the time it felt relentless, but now I think back to that time and miss it. And the reality is, it was such a short time.
Please don't fret
