Water and a small amount of sweets or one sugary drink and no sweets . Not both . Take a toothbrush with you . Need to get kids into good early habits . Lots of young kids getting tooth decay early . My mother is a dentist .
I would say at least 6 , preferably 7 any younger and they probably won’t concentrate for the whole game . My nephews certainly wouldn’t !
It’s also quite scary for any child younger than 6 to be in a big crowd with a lot of noise , it’s important to remember that .
