Start baby proofing! These are the 17 worst hazards in the home for kids

Curious toddlers may want to stick their fingers into floor vents. Wiggling them in is straightforward. Taking them out? Not so much. They may also drop items inside or lift the vent, which can be sharp or pinch tiny digits.

TIP: Try magnetic mesh vent covers or radiator guards. Childproof your HVAC registers by securing them with glue or screws. Fix a dryer sheet to the vent, or hide the vent under furniture that won't block airflow.
