Syd stays with her grandma when we are away...whether it be for just one night or a full vacation.
Our first vacation was about 3 weeks after we brought her home. She wasn't that attached to us yet and she fit right into life with grandma for a week. She didn't even seem to recognize us at first when we came to pick her up.
Since then, the longest we have been gone is over 1 night. She doesn't like being left...but she deals.
I am concerned that in 8 months we are getting married and Syd will be left with grandma for about 2 weeks solid. I'm afraid she will get depressed.
