Whats the best way to make a baby fall asleep?

Babies crave routine! So it's best to set a timeframe especially during nap and sleeping time. You can also use certain paraphernalia so they can learn to associate things with sleeping time. I have this lullaby projector. In the morning after some playing/watching time, my baby shows signs of sleepiness so I play the lullaby song. This signals that it's his nap time. Then at night, I clean him 30 mins or 1 hr before going to bed and play the lullaby song. I dim the lights and that's it. He sleeps the very same time every night of his life :) Make sure to tidy your baby ahead of time (before he gets too sleepy) because this may trigger crankiness.
