He gets good grades, had lots of friends (but can be a little bossy but maybe that's from being an only child), never gets in any serious trouble or uses profanity but he's very immature for his age. Most of the time he doesn't listen for crap until I either have to raise my voice or take something away, and he does display some hyper activity. I have to pretty much tell him to do everything or it will never get done on it's own (usually have to walk him through things) and he screws around too much...he's very silly even when it's time to be serious like during homework, and at restaurants but he's gotten a little better with that with age.
Believe me, I'm no push over and I have disciplined through the years in every way imaginable. Taking things away works the best for the time being but then he reverts right back to the way he was. It's like he NEVER learns. You could tell him 1,000 times not to do something and he will still do it. At 10 I shouldn't have to tell him not to jump on the couch 600 times.
Is this normal kid behavior? Is there an only child syndrome? He's physically 10 but behaves like he's 7.

I'm scared to death of what he may or may not be like as a teen. Anyone else have very difficult boys that turned out ok as teens or should I start drinking now?
I am a single parent and somehow feel like I failed him.

No matter what we did,what we took away...anything,he still wouldn't do his homework.Called it busy work and didn't understand why,if he could ace a test,he had to do busy work
We ended up putting him in adult education classes (no homework,everything done on the computer in his own time) and he passed everything with A's and months ahead of his class.He tested us every step of the way though...every.He's married now and living in Hawaii....and doing quite well actually.He's working and he and his wife have a little place to call their own.I wish he was closer,but for now he's living his life and enjoying himself...and I'm happy for him.My daughter-in-law's family is all out there...so I know they do have people to go to if they are having any difficult times...and they also know they have my husband and me.
I certainly did want to take up drinking for a couple of those years 
- I don't mean that laugh in a bad way, but I've just recently realized how silly I must look to "seasoned" parents when I have this bizarre "Really? They're actually LIKE that??" look on my face ...
It's tough too, because most of the time, he's a great, sweet, loving kid. But when he gets something in his head, there's no talking him out of it, and he will talk back to anyone who tries, including teachers.
