A phase III multicenter randomized double blind clinical trial will be conducted. After obtaining written consent the infant will be randomized, during the first two weeks of life, to a study group to receive either 400 IU or 1,000 IU / day of vitamin D to the year of age.

Baseline and all follow up visits (2, 6, and 12 months of life) will include anthropometric measurements and a questionnaire about health issues. A blood sample will be obtained at baseline for analysis of 25OH vitamin D, and at 6 and 12 months for analysis of 25 OH vitamin D, and calcium.
