Agree with youngblood

He is 5!!

he may grow up to be a Ballet Dancer

keeping him off the E numbers is a good thing anyway

Keep him interested in sport in general football will help his balance, Rugby will help his Bottle keep him going to boxing as long as he enjoys it, but don't keep telling him he is going to be a world champion if he gets knocked cold in the playground for gobbin off it will be your fault.

feedback on his talent or whether I am wasting my time.
If he is enjoying it you are not wasting your time and it doesn't matter whether he has talent or not, If I tell you he has a sloppy defence and shit footwork will you stop him playing

there is no rush if he is still keen at 12 then start looking for good trainers

For now let him go play with his mates
