My DS aged 3 had his first swimming lesson today, he was in a class of 7, 5 kids sat beautifully on the side of the pool listening and obeying the instructor, 1 child cried through half of the lesson while my DS moved around, talked to the other children, wandered off, shoved floats etc in the instructor's face. I was in a viewing gallery so he couldn't see me and I couldn't glare at him/tell him to sit still (not that it would have made any difference). I was utterly mortified by his behaviour, the instructor mostly ignored him and I do wonder if my DS was bored and that is why he played up. He goes to nursery and we constantly hear reports of how he hasn't listened during the day. If he is interested in something he can play beautifully but is rarely that interested in anything.
I am worried and don't really know how to tackle this - we have tried bribes, punishments, ignoring bad behaviour and don't know where to go next, please tell me it is just a phase and how to get him to listen
