We bought these 2 years ago at Christmas for my son who was 15 months old at the time. He is now over 3 years old, and he still plays with them a LOT. I have actually come back to order another set for my nephew who is turning a year old soon.
We bought these for our grandson at the suggestion of his mother. Both he and his sister played with them for hours (ages 1 1/2 and 2 1/2 - which is younger than the suggested ages...). They do no damage when knocked down or thrown. They are brightly colored and fun for the adults to "build towers" with. I would suggest them for any child.
