Forgive the length.
A little background:
My son is "young" for his year, he has just started at primary school after a year in nursery. His birthday is in early June. He is also an only child, and is highly likely to remain so (and only grandchild on both sides of the family at the moment). The statistically aware part of me realises these might be disadvantages for him. They might not be, but it's all context.
He is very strong willed, which personally I delight in, I'm hardly a shrinking violet and neither is my wife, but neither of us expose him to, or encourage, violence of any kind. We're both firmly of the opinion that violence is unacceptable as a way to interact with others. No matter HOW tempting! ;-)
He had a troubled start in nursery, crying, melting down, not interacting well etc. This gradually changed and by the end of the year he wasn't clinging to one teacher, melting down regularly etc. He was a normal, well adjusted kid in the class. Over the summer he was in a holiday club two or three days a week, and between myself, my wife and my in laws, we managed the rest of his care ourselves. He had a dramatic first day at holiday club, in line with his worst days of nursery, but after that behaved fine.
Cue first day of primary school, this Monday. Major meltdowns, crying, talking (shouting really) over the teachers, refusal to cooperate, hitting other children occasionally, the full spectrum. That was the morning, he'd settled in the afternoon. My wife and I were called into the school, of which more later. Tuesday was a better day, morning not perfect but he's 4, it's to be expected, afternoon better. This morning he hit another child for no obvious reason, simply ran over with a plastic toy and hit the child in the head which caused a small gash, which obviously bled. The school called and I had to take him out of school for the day.
Do I suspect he will calm down, get over this phase etc? Yes. That doesn't solve the present problem.
At nursery (and now primary school) the first instinct of the teachers was to medicalise the problem. I'm not averse to this, I actually work in a related field so I understand it, and I also grasp that this is a way to help my son. He's been seen by an educational psychologist (luckily on his worst day ever!) whilst at nursery, and the school recommended he see a paediatrician. The findings of the educational psychologist were that he was behind average in his emotional development (cognitively/intellectually he's ~ 1 to 2 years ahead of his age. He reads at a 5 to 6 year old level, and is similarly capable with his arithmetic, for example), and thus is having trouble relating socially and in regulating his emotions. The findings of the paediatrician were that he was a little lagging in his speech/conversation, but not out of normal range, and other than that, he was a "normal" little boy. Whatever "normal" means.
If he is autistic (a suspicion of a nursery TA) or has some other lag in his emotional regulation/speech/whatever, that's fine. It's just who he is, we'll have to do what we can to help. I confess I am a little disturbed that the first port of call for "child behaving poorly", even very poorly, is to try to find a medical reason. Like I said, I understand why, but it strikes me as a disproportionate reaction.
Lastly, this new primary school of his (a very good academy...the ethics of that aside) have a "zero tolerance policy" for violence as children move up the school. Already they have impressed upon us the seriousness of my son's actions and that should it continue to when he is ~6 or 7, he'll be excluded. Another reaction I find disproportionate. And yes, if some little brat hit my precious darling, I'd feel the same way, and indeed have felt the same way.
In all honesty I am scared. I don't want my child to hit anyone, that should go without saying, and obviously I don't want him excluded from a good local school I worked hard to get him into. I don't want to make the standard excuses for him, I want to resolve the problem as best I can.
I'd appreciate any advice people have on a) dealing with The Boy (little rascal that he is), and b) getting the most out of the school/dealing with the school.
