FI and I are planning to have no children at our wedding (except our siblings children which consists of my sister's son (ring barer) and her step-son). Most of my family lives on Cape Cod, MA where the wedding will take place.
My cousin *Jane lives in Vancouver with her husband and two daughters 8 and 16 and they are planning on coming to our wedding (5/5/12). The thing is if they are traveling that far to visit family it makes sense to bring the kids. They visit the cape once every 4 or 5 years but we communicate weekly through facebook/email.
Would we now have to invite children of other wedding guests? Or at least other family members' children? Or is it okay to only include my Canadian cousin's children because they are family AND from out of town/another country?
