Congratulations! Don't expect too much initially but you can encourage good sleep habits. Whether these help I really think depends on the baby's temperament. Both mine have been very different despite doing things 'wrong' for number 1 (who is a way better sleeper) and 'right' for number 2 who is a frickin nightmare even at 8 months.
Keep everything dark and quiet 7-7 and bright and noisy 7am-7pm.
Don't change nappies at night unless baby has pooed.
Don't worry about feeding to sleep for the first 12 weeks, but do try to think about getting him to sleep without feeding/rocking after this time. Don't beat yourself up if you can't.
Start a bedtime routine - eg bath, book, feed, sleep (which can be switched round to feed, bath, book, sleep after 4 months or so).
Use a dummy if you want.
There are something called the 5 s's, have a Google and use them when baby has his witching hour in the evening.
Go to bed as early as possible and nap if you can.
You might end up with a brilliant sleeper, you might end up with an awful one. I think it's a bit luck of the draw. I might get criticised for saying this, but the parents I know who can tolerate listening to the baby crying seem to have better sleepers. I have no problem with the theory of letting your baby cry a bit, but I am just way too soft and can't personally do it. And I have a seriously shit sleeper! Who to be fair has made some progress but very slowly.
Hope some.of that helps xx
