DS1 is turning 4. His "theme" is costume party (i.e. he wants all of his friends to dress up in costume). Would this bug you if you were a fellow 4 year old mama considering the birthday party would be in May (not October near Halloween where you'd have a costume on hand)?
Also, any suggestions on decorating and using this theme further?
I could buy a bunch of dress up type clothes and put them in a big trunk for kids to dress up at the party.
Any ideas would be helpful!
