Baby sleep routine

My son started sleeping full night from week 5. His doc said that its quite normal and babies learn to sleep full night sometime between month 2 to month 6 and he advised me to feed him only on demand and not to wake up a sleeping baby. I would put him to sleep at 11 pm and wake him up at 4 am for a feed (yes, I don't listen to the doctor at times)and the baby would wake up only by 8 am the next morning.

I have learnt that my son complies to a sleep routine if its followed regularly. 

After 10 pm at night, I strip him, give  him a quick warm sponge bath (or a full hot water bath if we had taken him out on travel), put a vest and a diaper on (which my mom calls as his night dress), set his cradle with the mosquito net, switch the light off and the night lamp on, play a lullaby in my mobile (I love Vatsalyam by Bombay Jayashree) and nurse him. He would either have fallen asleep or feel groggy. I would very gently place him on his cradle and cover with the  mosquito net. If he hasn't slept, then a mild rocking of the cradle for few minutes would do the trick. I follow this routine regularly and it works almost always. Thank God.
