In parenting, there should be no competition between a mother and father. It is not wise to manipulate our children so that they would prefer one parent than the other. We should use our mother-child relationship to strengthen father-child relationship and vice versa. It is important for a mother and father to have a united voice in parenting. If we truly love our children, we would set aside our differences and do what is best for our children.
Similarly, a family splintered by feuding will fall apart. Mark 3:25
