Summarize this article:

Observe your baby's natural schedule and find out what bedtime fits the best. Keeping a diary will be helpful for this too .  Do not play too much with a newborn before bedtime. It may be too stimulating, making it more difficult for the newborn to fall asleep. Give your baby a bath before bedtime and massage hr skin with some milk or baby oil. This will relax your baby before sleep. Sing your baby a lullaby or play some soft, quiet music to get her to sleep. Sing even you are not adept at singing. Your baby loves your voice and is not a music critic. Keep the rest of the house as quiet as possible at nighttime. A quiet, peaceful environment will indicate to your baby that this isn't just an ordinary nap. Put your baby to sleep in a dimly lit room. Do not turn off the lights completely. You always have to see your child. The darkened environment will help her to sleep through the night. The baby will probably wake up during the night. When this happens, take her in your arms, feed her and put her back to sleep. Do not change diapers, unless it is really necessary. That part is omitted from the night schedule, along with playing and cuddling.  If the baby does not wake during the night to eat, wake her. No matter how good it may sound to let a newborn sleep all night, it's not healthy for them. Babies need to eat every 2-3 hours. Otherwise, the baby may be dehydrated and hungry, which causes fatigue and weakness. It's important to stick to your schedule as much as possible, especially the going to bed and waking up times. In this way, it will be easier for your baby to get used to it. However, keep in mind that over time, your baby will sleep less and will require more of your attention and time.

Summary:
Set a time to sleep. At night, reduce the noise levels. Reduce the light. Prepare for your baby to wake up throughout the night. Stick to your schedule as much as possible.
