Actually I loved it - yes the lack of sleep was a challenge, but you get used to it; it maybe helped that I'd been waiting 10 years for a baby so I was determined to enjoy every minute of it, and despite my family's expectations I think I did ok.
I was prepared for it to be dreadful, my mum had been telling me for months that I'd never cope and that made me really anxious, but when DS arrived I somehow just got on with it, left all the stuff that wasn't important (tidying, cooking from scratch every day, thinking I needed to put everyone else first as usual) and just focussed on me and the small one.
DH was mostly helpful, and we worked out a "one night on, one night off" system so I always had a night's sleep to look forward to even if I'd been up all night the night before.
Me and DS fell into a relaxed routine (I know I was lucky that he was so easy), and of everything I remember from that time, the sleepy 4am feeds were the best, all snuggled up watching the sun come up and then both of us going back to bed for another three or four hours.
The best advice I had from the HV was to follow what DS wanted - let him set the pace and the routine rather than thinking it needed to work in a certain way. That worked brilliantly for us, within a couple of weeks I knew what he'd want when, and even when he went off-piste a few times it wasn't too long before we got back to our little pattern.
This isn't meant to sound smug, he was a dream baby and I know they don't all work like that...but get yourself as organised as possible - BF/formula all ready to go, nappies ready, clean clothes ready, a freezer full of easy heat-up food (I felt stupid making it, like I was over-reacting, but it was a godsend for the first three months), and then just enjoy as much of it as you can. If you're lucky it is a very special time, for me it was magical and the happiest I'd ever been.
Best of luck x
