Does the child really love Grandma more than Mom?
My daughter has an 18 month old girl. Clearly the child is coming into the terrible twos early. Tantrums and all I am told. (I live 2,000 miles away and do not get to be there as often as I would like.) So my daughter is struggling (as all moms do) to determine the best way to guide this energy in a positive direction.
When her mother in law (baby's "other" grandma) is around, the child is happy and cries when Grandma leaves the room, etc. My daughter takes this a sign that baby loves Grandma more than herself. While I do not believe this for a second, I have not been able to find the words to help my daughter put this is a better perspective.
So... all insights are welcome.
