Our six year old son joined the family by adoption, three years ago, and he is doing OK.
Theraplay helped a lot. His temper 'tantrums' have halved in a year.
He is NT (as far as we know) but can be pretty rude and moany. He must know how not to be since he can lovely to his lovely teacher!
Generally, he lets people know when he is not happy. It's hard to know how to deal with his 'moods' at times.
I''ve done lots of parenting courses and training and unusually know what to do but it is hard being patient all the time while someone is dismissive and rude.
Please be kind, it's been a long day. I don't mind so much for myself but.... He kind of makes it harder for himself.
I love him to bits but he sometimes shoots himself in the foot! By that I mean he wants play dates and then acts so moany I fear he will not get invited back!
