It's my nephew. He's 5 this year and going through a very naughty phase. My sil is at her wits end and very upset. He will not do as he is told, throws things, hits, kicks and spits. Everyday is a battle. He is however good at school. I have no experience of this but SIL is tearing her hair out so I thoght I'd ask wise mumsnetters.
TIA
