This is my honest impression: you seem pretty high maintenance. I would not be happy if my sibling local to grandma took grandma away from holliday visiting plans for a birthday party. I never expect any family member so stop their lives for a birthday celebration. If you were planning a huge party from way back when and made a point of getting your family to save the date, because this was going to be a special out of the ordinary birthday party, thats one thing. But to assume everyone is going to stick around for a birthday in the middle of the most busy, festive, time of the year is a little ridiculous. FYI my daughter's birthday is in mid december. I never assume that grandparents and aunties (who are local and always game to be their for their nieces celebrations), will be available in December with all the christmas parties and out of town family to see. If everyone had made other plans, we'd be fine celebrating with just our family. I don't think everyone needs to revolve around my child when they have other grandchildren, family, and lives to tend to. Especially to put off seeing out of town grandchildren to stick around for yet another special event for a local grandchild.
