Well for one thing, DH has to understand that you'll be a hormonal mess right now. There is nothing less rational than a new mother. He may not be able to sort things out practically - how do you "solve" an emotion? - but a cup of tea and a hug is often all that is required.
With regards to intimacy, most women won't feel like it for at least weeks and probably months after the birth. It's perfectly natural - your mind and body are all wrapped up in giving the current baby what it needs, not in preparing to gestate another one. It's important both that DH does not pressure you to get back with it before you're ready, but also that you let him know he is still loved and wanted. It's also important, IMO, that he lets you know you're still attractive too, not the same thing as insisting on sex! You're likely to feel your body has been devastated - all those saggy bits! - and although it will improve massively, there will be changes for ever, mostly for the better IMO; so you may take a while to adjust your body image, and meanwhile feel shy/embarrassed about it. DH will probably think it's gorgeous but you might have trouble believing him.
You will also both be tired and grumpy, however placid your baby is. DH probably will too. Try not to get into "competitive tiredness syndrome" but recognise it's tiredness that's doing it, and that your spouse is not the most irritating man/woman in the world, they're just the nearest person to take it out on. Try to support each other as much as possible. Earlier on, it's you who will need much more of the support, even if he does work hard/long hours/unsocial shifts. This baby is both of yours and although at first the mother is usually best placed to do the majority of care, particularly if bf, it is not only a duty but a privilege for the father to participate as fully as your domestic situation allows. He won't always do everything the same way you would, but as long as it's not life-threatening it's best to let him get on with it.
One or both of you may not bond with the baby immediately (though by the sound of it, you have). Just give it time, it doesn't always magically happen, but as you look after that real live human being you made (isn't that just too amazing?) you'll gradually find it really is the centre of the universe, and rightly so.
I bet about a hundred people have cross posted with better advice by now, let's just hit send and hope it helps...
