A bit more of the same as middle school but a bit more maturity for the most part.
There are more clubs and activities, more kids to meet and make friends with.
Possibly dating - and breaking up - and all the drama that comes with that.
And more rigorous classwork and homework - knowing how to use a planner is essential to keep on top of it.
You tend to think "it's only the freshman year of high school - he still has time" and while that's true - you/he also have to start thinking about his high school end game (college prep, trade school, etc) - what ever comes next.
For instance - freshman year is NOT TOO SOON to start taking the PSATs.
The more practice you get, the more you improve and the better final result when you take SATs (probably more than once) and ACTs.
As for privacy - no guests or visitors in any bedrooms - knock, wait for an answer before entering - same as you would expect him to enter your bedroom.
No electronics in bedroom beyond a lamp and maybe a clock radio - computers/ipads/cell phones, etc can charge in a public place in the house - kitchen, living room, home office, etc.
He's growing up - that means more responsibilities - doing his own laundry (our son started doing his at 12 yrs old) - some family cooking (there's no reason a son can't learn some basic cooking) - cleaning his bathroom - helping out with household tasks.
He's going to be getting a learners permit and learning to drive.
He should learn how to change a tire and top off car fluids.
You are shooting for 'well rounded'.
My Mom has always said that the job of being a parent is to slowly put yourself out of a job.
You start with a helpless infant and raise them to be self sufficient adults who are capable of raising kids of their own.
In 4 short years - and it will fly by faster than you think - he'll be moving out and living in a college dorm.
What does he need to learn between now and then?
Plenty!
You're at a different stage - but your job isn't over yet!
We'll be sending our son off to college this time next year.
His senior year is going to be a whirlwind of activity!
A lot of what's running through your mind is/has been running through mine.
I came across this site and like what I've read so far:
