Stanford's Outcomes Research in Kids

An intervention is nested within the observational cohort study as a secondary outcome. Commercially available household and personal cleaning products that either do not contain triclosan or that may contain triclosan will be delivered to the household every 4 months for the duration of the study. All cleaning products will be formulated, packaged and labeled by the original manufacturer with no modification for this study. Use of these products will be as per each individual product's label and at the discretion of the participant.
