My son decides what he'd like to do and finds it difficult to (doesn't) follow instructions.
It's been since he was about 2.
He's grown out of the toddler-ish behaviours (running around the outside of toddler music group, while all the other children join in and follow. Will he grow out of this?
It's very isolating to have a strong-willed child. He revels in the slightest friendship moment- but puts others off with his desire to do (and have them do) what it is that HE would like to do. Persuasive rather than pushy, he is charming with it. Conversations are also controlled - with an emphasis on talking vs listening and responding - also keen up get me to talk about things he is interested in.
I've posted about it before. Last week, he was aggressive for the very first time (he is 5 and a half) 
It was a tough week for him. He feels isolated and the children's seating arrangements at school were all changed. Could be guessing / justifying it.
Struggling and feeling paranoid in the playground - that's me. Lol
I just don't want mums to alienate him by talking badly of him / not inviting him on au dates. A teacher at the school is also a mum in my class - and a HUGE gossip).
