Children love playing with light. It creates a magical experience that offers new exploration and wonder into familiar spaces. Why not include them in your night time routine, reading stories with torches to create a space that's safe and special to just the people sharing it. It gives the illusion that it's just the two of you, and no one else can see in. Or why not bring them out on a evening walk, they will highlight exactly what your child is seeing and observing, literally showing light on their interests and wonderings.
