babyproofing

Babyproofing is the process of making a home or space safe for infants and toddlers by removing or securing potential hazards.

This typically involves installing cabinet locks, covering electrical outlets, padding sharp corners, and gating stairs.

The term can extend metaphorically to any effort to make something foolproof or protected against careless handling: We spent the weekend babyproofing the living room before the twins started crawling.
