I originally suspected my ds1 had adhd when he was 3/4 but put his behaviour down to being a lovely toddler.
He's now 10 and I'm struggling to decide whether I need to seek help for him or if he's a normal 10 year old. The issues we have are;
He doesn't listen-Anyone can tell him something and he'll ask a question about it a couple of minutes later-when he was just told the answer to his question
He's a little disruptive in class-talking,passing notes, messing with his ruler etc if he finds the lesson 'boring' then of course because he hasn't listened so doesn't know what to do
He forgets everything
He loses everything (3 x locker keys, pe kit, dinner pass since September)
He doesn't ever accept any responsibility for his actions-he got out the car once and his school bag strap was wrapped round his foot so he tripped and fell out of the car. He blamed the school and it was their fault-it wasn't an accident 
He has very little concentration
He fidgets and makes noise constantly-he humms while eating, fidgets while talking and sitting. He can't just sit in the car-he fidgets or hums.
He gets very frustrated with siblings and has aggressive outbursts
The only time he's still or quiet is on the Xbox or if he's watching a program he likes-and then he gets angry sometimes if you interrupt it.
He's very loving to animals and can be incredibly sweet and thoughtful.
Any thoughts?
