It had been quite effective until this evening. He deliberately weed on the naughty step, as his pyjamas weren't wet, so he must have pulled them down.
Not sure how to discipline him, he's being very unruly at the moment, and having particularly wild spates. He seems to behave worse than his peers, and people are starting to comment on his behaviour in group situations - he doesn't seem to be mean or spiteful to other kids, he just does daft things like picking up trays of pencils and emptying them on the floor. I sent him to the naughty step as he was sitting on my lap reading and he turned round and pulled my hair and knocked my glassess off .
