Roll out the Cotten wool eh! No sport is compulsory and they can choose not to do it . My grandson was bullied throughout his primary school ( who were totally useless at dealing with it ) by one particular boy ….then, my daughter enrolled him into a boxing club …which he thoroughly enjoyed , all precautionary measures were taken and he gained in confidence . He then went on to play rugby with a local youth team at 13….. They encouraged him to get stronger by light weights……amazingly the bullying stopped ( I didn’t ask how) ……You don’t do kids any favours by wrapping them in Cotten wool , or girls either! I know our instinct is to do that, but we have to overcome it . He’s 12 your grandson , not 2!
My brother broke his leg playing cricket when he was 12 ….i have had 3 breaks …one by stepping out of my front door !!!
Surely you do not want your grandkids to be coddled. It’s his choice , let him get on with it and CUDDLE him if he gets hurt ,but dont CODDLE him!
My grandson , now 16 , has gone on to play Volleyball and football, two much reasonabley safer sports , until he broke his finger last month ( volleyball) !!!
Life’s a risk …let them live it!!
