How to read this: comment counts cover the English comments on the first one or two comment pages of those videos. Gaps with a hook were checked by hand against the original comments; the other counts come from keyword rules and are rough. “Covered” checks video descriptions and captions, not what is shown on screen. For health, baby-safety or travel questions, show the label or the official rule; do not promise anything.
