Outcomes

Primary Outcomes

salivary cortisol

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.

Time frame: Baseline
