I’m thinking this will probably be the last year they will want their party together. They go to an extremely small school and know a lot of the same kids so it never feels disjointed but I also want them to get the special birthday treatment most kids enjoy. Another commenter suggestion of one party in the am and one in the pm could be a good compromise for this year though.
I really like this idea. At least for until they each have enough friends to warrant two separate birthday weekends
