Lauren does have an illness called Dyspraxia which had been mentioned on her before.
I googled the info which I have pasted below and could explain why Lauren is very often clumsy:

Developmental dyspraxia is an impairment or immaturity of the organisation of movement. It is an immaturity in the way that the brain processes information, which results in messages not being properly or fully transmitted. The term dyspraxia comes from the word praxis, which means 'doing, acting'. Dyspraxia affects the planning of what to do and how to do it. It is associated with problems of perception, language and thought.

Dyspraxia is thought to affect up to ten per cent of the population and up to two per cent severely. Males are four times more likely to be affected than females. Dyspraxia sometimes runs in families.

Other names for dyspraxia include Developmental Co-ordination Disorder (DCD), Perceptuo-Motor Dysfunction, and Motor Learning Difficulties. It used to be known as Minimal Brain Damage and Clumsy Child Syndrome.
