Indian sons are reared to take care of their parents and have a deep responsibility to family in general. Unfortunately, when a daughter-in-law enters into the picture it becomes a competition.

Of course, there are many daughter in laws who can and do return in kind. If you cannot win her affections or support, try to find it with other members of the family--starting with your husband.

His son is your daughter's son and therefore your grandson, and you are his grandparent.If your son-in-law's son is from a previous marriage, the son is not physically related to you.
