How you can establish your baby good sleep habits

Your baby can develop sleep habits as early as six weeks. At this age, these are some of the most effective things you can do to help your baby settle:
Learn the signs that mean he's tired
For the first six to eight weeks, your baby probably won't be able to stay up for much more than a couple of hours at a time. If you wait much longer than that to put him down, he'll be overtired and won't nod off easily.

Watch him for signs that he's sleepy. Is he rubbing his eyes, pulling on his ear, or developing faint, dark circles under his eyes?
If you spot these or any other signs of sleepiness, try putting him down in his cot or Moses basket. You'll soon develop a sixth sense about your baby's daily rhythms and patterns, and you'll know instinctively when he's ready for a nap.
Begin to teach him the difference between day and night
Some babies are night owls (something you may have had a hint of while you were pregnant) and will be wide awake just when you're ready to snuggle into bed. For the first few days, you won't be able to do much about this. But once your baby is about two weeks old, you can start teaching him to tell night from day.
In the daytime, when he's alert:
Play with him as much as you can.
Make daytime feeds social. Chat and sing to him as you feed him.
Keep the house and his room light and bright.
Don't try to cut out every-day noises, such as listening to the radio or putting on the washing machine.
Wake him gently if he nods off during a feed.
At night-time:
Stay quiet and subdued when you feed him at night.
Keep lights and noise low, and don't talk to him too much.
Before too long he should begin to work out that night-time is for sleeping (Sleep 2003).
