Your baby needs to feed every few hours around the clock, so it’s common and 
healthy for the baby to sleep for just a few hours. Be punctually to his cries, feed and sleep when the baby does to reduce your own sleep deficiency.
Starting 7weeks, you can strengthen your baby biological rhythms by set up a regular bedtime habit. Do routine at the same time every night like give baby a warm bath, tell story, read a book, and then feed him before putting him to bed and sing a song while sleeping. Try to get up your baby at the same time every morning and put him down for naps at the same time in the day.
At this phase regular in routine and your baby’s sleep timetable as a work in development. For the period of the first three months of life, your baby will gradually sleep more at night and less at the day. You’ll need to keep regulate the timetable as your baby grown-up.
By age of 3 months or as a result, babies have started to develop more of a regular sleep or wake up pattern and have reduces most of their night feedings. And somewhere between 4 and 6 months, most of babies are ready for sleep training and are capable of sleeping through the night for a stretch of 8 to 12 hours.
Every baby is different in behavior; some may be ready earlier, others afterward. And some will sleep seven hours or longer at an early age while others won’t do so until they’re much grown-up.
Before starting sleep training, make sure your baby doesn’t have any medical circumstances that affect his sleep. Then be flexible about how you apply your selected program and carefully watch how your baby responds. If the baby very resistant or you see a change for the not as good as in his overall mood and behavior, stop and wait a few weeks earlier than annoying another time.
