I just saw these hints in an article on helping babies sleep. (Why was I reading an article on this subject? No reason.) Notice the parts of the hints I marked in bold:
# Put your baby to bed drowsy but awake. This will help your baby associate bed with the process of falling asleep. Remember to place your baby to sleep on his or her back, and clear the crib or bassinet of blankets and other soft items.
# Give your baby time to settle down. Your baby may fuss or cry before finding a comfortable position and falling asleep. If the crying doesn’t stop, speak to your baby calmly and stroke his or her back. Your reassuring presence may be all your baby needs to fall asleep.
