William gets frustrated with everything. If he isn't directly involved in the action then he wants to be NOW. In years to come the will probably call him 'cranky Bill Duncan' who is way too much like his grandfather.
He can also be so funny. He has recently started dancing every time he hears music. He laughs and laughs at Jack and he makes Jack laugh too.
The way to William's heart is with water and food. He drinks water like a fish and plays happily in the bath or baby pool for over an hour. Fruit is his favourite thing to eat. Even above cake!
