Infantile colic is a common condition characterized by unexplained, inconsolable crying episodes in otherwise healthy infants without any identifiable cause. It can lead to significant parental distress, increase the risk of child abuse, and contribute to early cessation of breastfeeding. According to Wessel's criteria, also known as the "rule of threes," colic is defined as episodes of irritability, fussing, or crying lasting at least 3 hours per day, on 3 or more days per week, for at least 1 week, in an otherwise healthy infant aged 2 weeks to 4 months.

Vitamin D deficiency is increasingly recognized as a global public health problem affecting infants, children, and adolescents. Recent pooled data suggest that low serum 25-hydroxyvitamin D [25(OH)D] concentrations remain common across many regions of the world, including low and middle income countries. In India, suboptimal vitamin D status is frequent in children, adolescents, and pregnant or lactating mothers, often coexisting with inadequate dietary calcium intake.
