I remember when our DD was not quite 18 months and all of us on my dad's side of the family were at his parents' house on the farm. No other grandkids. I almost cried when my grandparents wanted to give DD some little thing and tell her Santy Claus brought it to their house for her. Even then I was thinking about how confused she would be to learn that Santa Claus visited more than one location for her. My mom told me then to make decisions on what we wanted to do as a (new) family and where we wanted to be. I hated making my grandpa and grandma not be able to say what they thought was an innocent thing to a not-quite toddler. And we always made our own decisions from that point forward for holiday traditions for us. Hard to do at first, but I knew my parents would be behind us no matter what we chose. You will undoubtedly be fine, too. Just plan on ear plugs and more electronic visiting, along with band aids.
