Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Transitional formulas (22 kcal/oz) are recommended for infants less than 35 weeks gestation at birth. However, few data are available related to follow-up of infants receiving these formulas who were 28-34 weeks gestation at birth.

Primary hypothesis: Provision of supplemental vitamin D to a transitional formula will lead to higher serum 25-hydroxyvitamin D (25-OHD) levels and no infant with a serum 25-OHD less than 20 ng/mL when assessed at approximately 52 weeks post-menstrual age (PMA).

Investigational Nutrition

Starting between post menstrual age (PMA) 34 0/7 to 38 6/7 weeks, infants in the Investigational Nutrition group will receive vitamin D drops that are added to transitional formula daily through hospital discharge and at home until the outpatient follow-up visit at 52 weeks PMA.

Routine Nutrition

Starting between post menstrual age (PMA) 34 0/7 to 38 6/7 weeks, infants in the Routine Nutrition group will receive placebo drops that are added to transitional formula daily through hospital discharge and at home until the outpatient follow-up visit at 52 weeks PMA.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Born at 28 0/7 to 34 6/7 weeks PMA and 1000-2250 g birth weight.
* Currently 34 0/7 to 38 6/7 weeks post-menstrual age at time of consent.
* Born at Texas Children's (including Pavilion for Women) or Methodist campus hospitals or transferred within 48 hours of birth.
* Care expected to be provided at one of these institutions until discharge home.
* Any initial feeding will be permitted, but expected to transition to primarily (80% of feeds or up to 2 breast milk feeds per day) infant formula by 38 6/7 weeks PMA or hospital discharge, whichever comes first.
* Able to tolerate 22 kcal/oz transitional formula and receive a volume of at least 130 mL/kg/day total feeding volume.
* No longer receiving any form of mechanical ventilation or diuretics. Low flow nasal cannula (\< ¼ LPM) will be permitted if it is anticipated this will be discontinued before hospital discharge.

Exclusion Criteria

* Bronchopulmonary dysplasia (BPD) requiring daily use of diuretics beyond 38 6/7 weeks PMA (or hospital discharge, whichever comes first) and \> 22 kcal/oz concentration formula beyond 38 6/7 weeks PMA.
* Major congenital anomalies, history of proven Stage 2 or above NEC, or severe feeding intolerance.
* Caloric density greater than 22 kcal/oz.
* Higher order multiples (However, twins are acceptable. Twins will be randomized together. Only data from 1 twin picked at random will be used in the final analyses.)
