This study is to explore the dynamics underlying mothering development by applying the Object Relations Theorist, Mahler’s perspective and feminist psychoanalyst, Chodorow’s perspective, and to explore the implications to Christian counseling. As Mahler views infant’s developmental process as ‘the Psychological Birth’, so this process is also mother’s process of ‘the Psychological Birth’. As Child is fulfilling the separation–individuation, so mother does in the relationship with her child. The identity that the mother experiences can be explained by the identity formed by the dual identification mechanism explained by Chodorow. In other words, the children’s identity of original family and mother’s identity of her own children have an impact with each other, so healthy or unhealthy mothering development may occur. In conclusion, explanation of mothering development based on the concept of separation–individuation and double identification has a clinical implication, in that women, who became mother not accomplish separation–individuation from her original family, can grow to mother who can do separate–individuate from her child. Based on the results of this study, the implications for Christian counseling were discussed.
