Most kids have fun playing with blocks. It is doubtful that any of them realize that stacking blocks into a tower is actually an important developmental test. Making a tower of blocks is usually considered to be a visual-motor/problem solving milestone, and most kids can make a tower of:
  • 2 blocks by 15 to 21 months
  • 4 blocks by 17 to 24 months
  • 6 blocks by 18 to 30 months
  • 8 blocks by 24 to 36 months
  • 9 blocks after 3 years
