To express for DS so soon?

[Greywalls12]

DS only 3 days old, EBF so far and I'm absolutely exhausted and really struggling with the lack of sleep.
Feels like he constantly wants to be fed, which i know is normal but i think a lot of it is feeding for comfort as well, which i know is also normal but I'm just so sleep deprived!
WIBU to start expressing so DH can do some of the feeds?
But then I'm worried about nipple confusion etc and if he won't breastfeed again because of taking a bottle.
Breastfeeding in itself is fine, not that painful and he latches on well, it's just the lack of sleep! :(

Any words of wisdom or encouragement?

I found day 3 the hardest with both babies! Pick something relaxing and compelling to watch on your phone (first dates for me!), headphones, and feed when the baby wants to. Keep food and drink by the bed. And I was about to write what the two above wrote- stay in bed, eat, get others to take the baby out in the buggy!
