Oil-filled radiators are the safest option for baby rooms, as they heat up slowly, maintain a steady temperature, and have features like auto-shutoff and tip-over protection. Popular models include Bajaj and Havells heaters, priced between ₹2,800 and ₹3,500. Avoid halogen heaters, as their heating elements can reach dangerously high temperatures, posing burn risks. Thermostat-controlled heaters are also a good choice, as they prevent overheating and save electricity.
