Why do this?
The main aim of this activity is to offer your little one an experience of sensory stimulation as they look at the lights.
However, this activity also helps with emotional regulation as your little one can calm down looking at the little lights. If your little one is a baby, then this is a great activity for tummy time or helping them turn their heads right and left.
And if your little one is a toddler, then it's a great activity for imaginative play!
