When he started nursery he was so shy & quiet, also at soft play/on holiday he struggled to make friends due to shyness. In the last year he has completely changed into an overbearing over confident naughty child. It doesn't matter what punishment he is given, he just doesn't seem to care. His school reports are bad, he is so cheeky to me & other family members. Everyone is commenting on the change. There have been no big changes in his life, we're extremely close as its just us. The school have said he's a nice kid but very easily led. He genuinely swells when I praise him so I try to praise him as much as possible but with his bad behaviour it's not very often. Iv took all his favourite things off him but still no difference. It's getting to the point where people don't want to invite us due to his behaviour. I'm praying it's a phase but what if it's not?
