K.I.
A.,
So she's one this year, it won't matter, but DO NOT make a habit of it. Let her have her special day. As one whose birthday is "close to Thanksgiving" (a week later), I often did not get a special celebration while I was growing up. Half my relatives thought my birthday was "so close" to Christmas that they skipped my birthday entirely and gave me one gift at Christmas! I've known people with a 26 Dec birthday complain about lack of fanfare, but come on, why should we miss just due to being sorta close to Thanksgiving?
Best wishes,
K.
