Ok. My DS1 will be turning the big 5 in April and I'm pretty sure its during school holidays which is awesome, but this is the first year where he will have actual friends to invite. I have no idea how this works!? Isit rude to only invite a few friends or do you invite everyone? I have no idea where to have it, been lucky the last 4 years with no rain but you never know in autumn. Whats the going attendance rate for school friends? Im worried if I dont invite quite a few that people wont come then end up with no one there.
