It is understandable that you are worried about this. I had similar concerns before I had my first born.
I actually felt far less tired with a newborn than I did while pregnant. It is true that you are up and down in the night, but in between you do actually get some decent dollops of sleep in between.
Also, when you are breastfeeding, your body releases all these clever hormones and chemicals that make it easier to get up with your baby, and much, much faster to fall back into a deep sleep after feeding.
Before having our first, dh and I had discussed the fact that he needs much less sleep than me and we therefore decided that he would be the one to get up in the night and bring the baby to me, and put her back to bed - in actual fact once the baby was born, dh found it impossible to cope with continually broken sleep followed by a day at work, whereas I actually found it okay. I mean, yes, I was tired but I could cope. And this was with a husband who desperately wanted to help in every single way possible. You may find that you bottle feed only to end up doing it all yourself anyway.
I found what I most appreciated was him doing the early mornings so I could get an extra hour or so after the 1st feed of the day.
I don't have any experience of bottle feeding, but I understand that when giving a bottle n the night it involves going downstairs to make the bottle every time. The huge advantage of breastfeeding is that it's all right there - truly, it is the lazy persons feeding method of choice!
Also, you have the opportunity of co-sleeping which means you can feed and doze lying down.
It's not always easy, and I didn't have an easy time breastfeeding my first. It can be daunting. But with a bit of extra confidence and support, with my second I had him in bed with me latching on and off as he needed to and I got a decent amount of sleep.
Plus, of course, doing ALL the night time feeds is most excellent leverage for every pooey nappy and super-vom that you don't fancy cleaning up yourself becaise you're 'quiet tired'
.
Good luck!
