We were given one of these as a present. it is brilliant - so informative and very amusing too. So far my son has been the height for free new York bus travel, the height of a male adult baboon, a wheelie bin and a Komodo dragon amongst other things! He loves it and so do visitors. it has also really helped develop an understanding of height, comparisons and centimetres. Have since bought several as presents. it's a shame we didn't record the dates of the various heights on the chart as it would be fun to look back on in years to come.
