According to recent studies, we want to find evidences that infant colics could be a episodic symptom associated to migraine as cyclic vomiting syndrome or abdominal migraine are. The main purpose is to compare the presence of colics in infants between 60 days and 180 days of life and the presence of migraine in their parents to determine if colicky children's parents are more migrainous than other parents.

Recent studies shows that :

• Infants with colics have more probability to become migrainous when they will grow up
• Migrainous children have more colic history in their past
• Migrainous parents have more babies with colics than non-migrainous parents

Recently, the international classification of headache disease IIIbeta added in its appendix colics in the episodic symptoms associated to migraine
