Yep, kids always turn it on for their parents! Honestly, I think you should feel proud that your little bloke is behaving so well when he is outside the home and away from you. It would be much worse if they kept telling you he was always naughty. I don't think it matters that they comment in front of him about his positive behaviour - he's too little to get a big head about it!

Your family and the people closest to you know that he is not always 'easy' (what kid is??) and I hope they support you when it is difficult.
