That´s it, really. He is ok at school, but then refuses to meet friends with kids his age, or even attend his school friends´ birthday parties. If i manage to persuade him he´ll be asking to home home within minutes. He says he needs no friends as he has me, his dad and big sister... He adores adult friends and my parents, and could spend all day chatting to them. He also has been having horrible tantrums for the last few months, but I´ve just seen a couple of other threads about this of MN concerning 4 year olds, so maybe that´s normal... or could be related. He is extremely bright and creative and loves doing things on his own. I´m just a bit concerned now...
