Sleep is especially important for young children: they need it to recuperate the energy spent during their daily activities and to encourage their neuro-psychological development. They should never be interrupted, even if it is meal time, because babies are able to immediately adjust their instinctive biological rhythms and wake up spontaneously when they are hungry.
To help children sleep, whether day or night, make sure that the environment in which they sleep is peaceful, but not too quiet, so that they get used to the common noises within the home; especially in the daytime, limit but don’t put off all your normal activities in the home, and do not make the environment too dark, so that your baby gets used to distinguishing daytime naps from night time sleep and gradually acquires his own sleep - wake pattern.
Put the baby in his crib in the supine position (on his back).
Before babies fall asleep, talk to them softly and sing a lullaby as it is important for them to have the perception of being in the crib and not in your arms as the last thing they remember before falling asleep: if they should wake up during the night, they will not feel they are in a strange environment.
