Your baby's eyes are not yet used to brightness. Installing a sun visor on the window will prevent your child from being dazzled in the car. There are several types of sunshades: those that are attached to the car window with a suction cup and those that are slipped on like a sock on the car door to open the window. The benefits of using a car window shade are many, including reducing the heat and light inside the car to help baby fall asleep.
Baby's safety is the top priority. It is important to note that the use of a car window shade should not obstruct the view of the driver or passengers, nor interfere with the safety of the vehicle.
