We bought this tower about half a year for our son. Initially, it was therefore difficult to use the whole tower. So the little one has always viewed the colorful rings with a lot of enthusiasm. When it came to getting around, the rings came back into use: They can roll around and our son crawls always running. He could play for hours, throw it away, watching, after crawling. In the playpen then the whole tower is used, everything will be taken apart and thoroughly investigated. Gradually, therefore, with 9 to 10 months will be strung and stacked. Every child is different, but there are many different forms of play for this tower, and every child is so invent his own games. Highly recommended and timeless!
