"7+ tutoring. Too early?"
If you'd asked me, I would say it's 7 years too late!
But seriously, I'm on record here to say I "tutored" my child the day he was born! People asked me how do I tutor a newborn? Obviously not Maths, or English, or reading, or spelling, etc. On the first day, amongst other things, I stimulate him, e.g. talk to him, call his name, let him listen to music, let him grasp my finger, etc, etc, etcetera. . .
This tutoring went on the next day, and the next day and the next. I teach him new things as he gets older e.g. hold up a toy and let his eyes follow the toy when I move it slightly away from his gaze. Obviously, new lessons are taught as time goes by. Soon he's taught how to crawl, sit, stand, walk, etc. Much later on, how to use cutlery when eating, and then how to tie his shoe laces. Before long, I'd be "tutoring" him reading, spelling, maths, etc. and progressing in difficulty as he grows older.
Long story short, by the age of five, he'd have a reading and mental age of 13+ (officially tested by an educational psychologist over a week) and became a fully paid-up member of British Mensa before six.
My point here is: It's NEVER too early to tutor a child!
