Strong kicks and eyes that follow light.

  • Pupils at work
    The pupils now react to light, widening and narrowing like yours do.
  • Power moves
    Muscles are strong now; kicks and rolls are unmistakable and have their own daily pattern worth knowing.
  • A maturing brain
    The brain surface is folding into its grooves, making room for billions of connections.
