Are they both boys? Girls? One of each?
The reason I ask is because if they are into the same thing (sports, dolls, cartoons, etc) you could go with that for a theme for both of them. Or even better yet, do what I do for my boys (2 & 4) take them to a Dollar Store and let them pick out what theme they both want. Now, it is more complicated if you have one of each, but go with a netural theme (light green, etc) and have fun.
As far as what to eat: SANDWICHES and FINGER foods (they both will love that)..
Games: again go with the whole " what they are into" theme.
Best of luck
