I'm not big into birthday parties, I don't really enjoy having them or going to them, but this will be DS1's 5th birthday, kind of a milestone IMO. If we have 1 party with family and friends it would be around 50+ people invited (though I'm sure not all would attend). Our house is too small to accommodate that many (we'd probably max out at 20-30). I'm not sure if a park would be fun for all age groups. His birthday is (Saturday) 09/15, I'd like to keep it within a week or so. Should I split it up into a family party and have a separate friends party?
