Any advice on how to curb my 3 year olds behaviour would be appreciated. My 3 year old (turned 3 in feb) is hard work and pushes my buttons all day everyday! Today he has played up around the supermarket (running away, making silly noises) then we had a opticians appointment and he was not listening to the lady and been rude. (He knows what he's doing). Now he's just threw a stone at the conservatory window and broke it. Shattered to pieces. I told him off and asked him why he did it and he said 'cus i did' i said why did you throw it he said 'to break the window'! Today is one of his worser days but everyday he pushes my buttons. Im at my wits end. How do i curb his behaviour?
