It's hard because you both have to learn to do it.
I think that that is something that really isn't made as clear as it could be.
My first took AGES to sort. So painful.
Fuss fuss, latch latch, different positions, midwife clucking, try rugby ball.
Nothing sorted it but time and lots and lots and lots of skin to skin IN PEACE AND QUIET, ALONE! - with nobody fussing and distracting and hovering with their voices/strokes/perfume etc.
Of course lots of times there is an issue such as tongue tie, and it helps lots to get advice on latching and how to notice if things aren't as they should be.
But also, remember that it is ALWAYS going to be hard at the beginning. Rarely is it without difficulty and PAIN at first.
If your baby loves the breat, and if you know she is getting milk, you are 3/4 of the way there. Feed and feed, stay in bed, let her learn her technique with no distractions as much as possible. Let her get your supply going. Don't be afraid to prioritise feeding and sleeping as much as possible. If staying in bed all morning and feeding means that you can drop straight off for a nap as soon as she does, then stay in bed rather than get yourself out to a cafe. Arguably, she's actually going to feed less well in a noisy, bright environment - I'd really leave that until she's a bit bigger.
I am sure you will be ok. But it WILL be hard at first and that does not necessarily mean something is wrong or non-optimal.
