Over the past decade, development in childcare has drastically evolved. Technology advancements are responsible for many of these developments. Fifty years ago, daycares were slim and few. Daycare consisted of staying at a relative's or friend's home while your parents or caretaker worked. When daycares became more familiar to cities, children of all ages were placed in one room and taught the same lessons. Today, children are placed in rooms according to age groups and taught lessons according to their brain development. A few studies include hand-eye coordination, learning a second lesson, and learning different shapes. Children's growth continues to thrive as technology continues to advance.
