Infants – to about 4 months – cry because of physical needs. They can’t be “spoiled” at this age, so when your infant cries, pick him up and give comfort by rocking and cuddling. When your infant wakes up at night, take care of him quickly and matter-of-factly, without much social contact or play. Then put him back in the crib and leave the room, to discourage waking up for the rewards of play and attention.
