We don't know why some children have dyspraxia. However, for any human ability there is a broad range of 'normal', with an average, and some of us more or less able than others. Just as some children have much better co-ordination than average (including some who, for example, go on to become successful sportspeople or dancers), others may have much worse co-ordination. This means there is a wide spectrum of motor co-ordination development, from very poor to very good. When this development is markedly impaired, we term it dyspraxia, as we realise it represents a real challenge to your child.
