How important is light and darkness for my toddler’s sleep?

Blackout curtains are the best option for blocking out light. They are specially designed to block out sunlight and other forms of light, making them perfect for children's bedrooms or any room where you need complete darkness for sleeping. Look for curtains made with heavy, tightly woven fabrics, such as polyester or cotton twill, that have a lining specifically designed to block out light. Additionally, you can also consider curtains with thermal insulation to keep the room cool or warm as per the weather.
