Cry Babies

Colicky infants who cry for more than three hours a day can drive parents crazy and if your baby was born small (less than three kilograms), you could be in for more trouble.
According to Danish researchers, infants with low birth weight are more than twice as likely to develop colic than babies born at normal weight.
Study findings also showed that maternal age over 35 and maternal smoking were linked to an increased incidence of colic.
