MISSISSIPPI: I have an ongoing conflict with my mother-in-law. My wife and I have 3 kids, one being my step-daughter. Well, my mother-in-law seems to believe that she can take the child from me or have full authority over her when my wife is not around. She says she is blood kin and I am nothing. She has even tried to jerk the child away from my wife and she seems to believe that she has some rights to do so. I thought that even though the child is my step daughter that when she is with me I have full authority because she was left with me by her mother. I also consider anyone trying to pull child away from my arms is a threat of bodily harm. Am I correct in both of these instances??????
