OK, so it's not often that I (a full time teacher) get the opportunity to watch DS (3.9) be a learner but this summer hols he's been doing Sport for Tots sessions every week (45 mins of sport related skills, designed for under-5s) and I've been taking him. First week was rugby, second week hockey, today was tennis. They're obviously not doing full blown competitive team games but it's just focusing on their motor skills and team work and - and this is the crux of my post - their listening skills.
DS is a totally normal 3 year old in pretty much every way but watching him in the group has been painful as he is that kid (any other teacher out there might know what I mean). The one who is fidgeting, paying no attention, fiddling with other kids, chattering on about irrelevant stuff and distracting everyone, and who has to have every single instruction repeated for him specifically, much to everyone's amusement 
Two weeks running the instructor has had to (very nicely) move him away from another little boy because DS won't leave him alone 
It is very cute when DS interrupts the (incredibly kind and patient) instructor to shout "I love you mummy" at me but maybe only the first couple of times, not five or six!
It's not that he needs a pee or any other physical need. He's not the youngest in the group or the only boy or anything like that. He knows other kids there from nursery so it's not that he's ill at ease. He's obviously enjoying himself and he's a very physical kid who loves almost any sort of activity, he just doesn't listen! And he's not deaf either; he can hear an offer of chocolate cake whispered half a mile away.
I really don't want him to grow up to be the kid who is always a step behind because he hasn't listened to the instructions, I know exactly how that can affect a child's progress as they get older. So my question is, what do I do to improve his listening skills at home? Are there any games we can play? Or am I being all PFB and he'll just grow out of it?
