Objectives: (i) To measure 25‐OH vitamin D levels in term infants at 10 weeks and 6 months and to correlate with maternal vitamin D levels at 10‐week postpartum (ii) To evaluate infants at 6 months for rickets. Patients and methods: A total of 179 exclusively breastfed infant–mother pairs 96 appropriate‐for‐gestational age (Group 1) and 83 small‐ for‐ gestational age infants (Group 2) recruited at 10 weeks. At 6 months, 52 in group 1 and 45 in group 2 were evaluated. Venous blood sample were collected at 10 weeks and 6 months in infants and at 10 weeks in mothers for calcium, phosphorus, alkaline phosphatase and 25‐OH vitamin D estimation. Results: Mean 25‐OH vitamin D levels of infants (n = 97) were 11.55 ± 7.17 ng/mL at 10 weeks and 16.96 ± 13.33 ng/mL at 6 months (p < 0.001). Mean vitamin D levels of infants in group 1 and group 2 did not differ at recruitment and 6 months (p > 0.05)). Maternal vitamin D levels in group 1 and group 2 were 8.89 ± 5.97 and 9.87 ± 6.44 ng/mL, respectively (p = 0.44). Significant correlation was observed between 25‐OH vitamin D of infants and mothers (p < 0.05). At 10 weeks, 55.67% infants, 70% mothers and at 6 months, 44.33% infants had vitamin D < 11 ng/mL. At 6 months, 16.49% infants developed rickets. Conclusions: Exclusively breastfed infants and their mothers are Vitamin D deficient, hence the need to improve vitamin D status.
