Primary outcomes

  1. salivary cortisol

    Time frame: Baseline

    Study will be assessing babies' neuroendocrine responses to play vs TV viewing. Salivary cortisol, as an indicator of neuroendocrine response, will be measured over time with the intervals as specified under time frame. For each time point, investigator will adjust for prior ones in a repeated measures analysis.

  2. salivary cortisol

    Time frame: 10 minutes post baseline

    Study will be assessing babies' neuroendocrine responses to play vs TV viewing. Salivary cortisol, as an indicator of neuroendocrine response, will be measured over time with the intervals as specified under time frame. For each time point, investigator will adjust for prior ones in a repeated measures analysis

  3. salivary cortisol

    Time frame: 20 minutes post baseline

    Study will be assessing babies' neuroendocrine responses to play vs TV viewing. Salivary cortisol, as an indicator of neuroendocrine response, will be measured over time with the intervals as specified under time frame. For each time point, investigator will adjust for prior ones in a repeated measures analysis

  4. salivary cortisol

    Time frame: 30 minutes post baseline

    Study will be assessing babies' neuroendocrine responses to play vs TV viewing. Salivary cortisol, as an indicator of neuroendocrine response, will be measured over time with the intervals as specified under time frame. For each time point, investigator will adjust for prior ones in a repeated measures analysis

  5. salivary cortisol

    Time frame: 40 minutes post baseline

    Study will be assessing babies' neuroendocrine responses to play vs TV viewing. Salivary cortisol, as an indicator of neuroendocrine response, will be measured over time with the intervals as specified under time frame. For each time point, investigator will adjust for prior ones in a repeated measures analysis
