You've had loads of good advice there, just wanted to add my experience.
I used reusables from 4 weeks with DD. It was a big mistake for us. I'd researched and bought new, because they were on offer, and then they just didn't suit her at all. I dreaded everything to do with nappies because I hated the way they fitted her, the great bulk of them and the way all her gorgeous little clothes just did not fit. I ended up selling them so lost about £100 in total as I had got a whole load for birth to potty.
It was also January and nothing would dry. I washed every day, then hung indoors on an airer with a dehumidifier running 24/7 next to it, and the 20 nappies I had were not ever dry. And despite soaking them, using liners which I rinsed first and being careful with detergent etc, I ended up with a sludgy brown buildup in the washing machine every single time. I honestly lost track of the times I sat with DD crying and myself crying, because I 'couldn't do it'.
It was only when DH came home and found me like that, demanded to know what was wrong and I told him that I hated the nappies and everything to do with it, but I'd spent £££ on them and felt such a failure, that he went out and bought a load of disposables and said, problem solved. Of course there's the environment to consider, but it was getting to the point that I was becoming unwell and unhappy with DD, over something so silly.
So by all means try it. But I would go slowly, don't spend a load, look at second hand and different brands to find what suits you. I would also avoid the first few weeks as meconium is truly something else! Not to mention, you don't know how things might go with your birth and yes, you will be completely lost with regards to day, night, feeds, sleep, even if all goes smoothly. It's one less thing to have to deal with, which might sound trite but in those early days even the smallest thing to make life easier is worth it, IMO.
I would also be cautious about using reusables in hospital, purely because there is zero space in your bed area. Yes your OH could remove dirty and bring fresh daily, but what if you're in for some time? Newborns get through 8+ nappies a day easily, and they are really sticky, gloppy, nasty things too. It just feels like a lot of pressure that can be avoided when so much else is going on.
Good luck whatever you decide!
