This is the probably the best $15 I've ever spent. Since we got this when my son was 14 months he has loved building up and knocking down the tower over and over - it's so much fun for them. The cardboard has its benefits and downsides - our cat likes to chew on them a little because of the paper, but otherwise they are great because they are lightweight (and virtually impossible to get hurt with them) and surprisingly durable. I bought a second one to give as the perfect gift for a one year old. Definitely don't need to wait until 2.
