She told the court when they were not in a good mood, they treated him 'badly'. She said: 'They were always throwing him about and telling him off. (They would) pick him up and throw him on the sofa, both of them. 'They would both literally just pick him up by his arms or slap him round the head. I saw both of them do it.'
