I'm hosting a 9th birthday party for DS and his friends. I usually provide jugs of squash but for logistical reasons this won't be possible so I need to buy some bottled drinks. What do your 9 year-olds like to drink?! DS often asks us for coke and we only let him have it on special occasions - we don't want to serve coke or other fizzy drinks to all his friends, in case the parents aren't comfortable with it. DS still quite likes Fruit Shoots but are they getting a bit babyish now?! What else can I get...
