My kids seem to be following in my footsteps which is partly due to me and partly due to their dad being 6ft 1. In her class my daughter is one of the tallest and comes on the 75th centile on the growth charts. My son at nursery towers above most of his class and is taller than children 2-3 years older being on the 98th centile.
As I can't remember my exact height until I was 10 - I was level with my mum who was 5ft 4 - its not easy to compare how they match up to me yet as they are only 7 and 4 respectively. However by looking at photographs I can see myself in relation to other people and then compare this with my kids today.
