Primary Outcome Measures:
  • Enrollment and Trial Completion [ Time Frame: Pre-baseline to 180 days post-randomization ] [ Designated as safety issue: No ]
    The number of children who enroll in the trial and the proportion who return for study visits 2 and 3.

  • Adherence [ Time Frame: Baseline to 180 days post-randomization ] [ Designated as safety issue: No ]
    The proportion of children who adhere to the assigned supplement or placebo.

  • Fatty Acid [ Time Frame: Baseline to 180 days post-randomization ] [ Designated as safety issue: No ]
    Change in plasma and RBC fatty acid concentrations.

Secondary Outcome Measures:
  • Development [ Time Frame: Baseline to 180 days post-randomization ] [ Designated as safety issue: No ]
    Changes in Bayley Scales of Infant and Toddler Development - 3rd edition scores from baseline to study visit 3.

Other Outcome Measures:
  • Behavior [ Time Frame: Post-randomization ] [ Designated as safety issue: No ]
