Throughout the Ayodhyā and other Kāṇḍas or the Vālmīki Rāmāyaṇam , Sumitrā and Kaikeyī are mentioned as the middle mothers of Lord Rāma. somewhere Sumitrā is called the middle mother and somewhere Kaikeyī is called the Middle mother. Is there any interpolation in the Rāmāyaṇa because of which these confusions arise?
Please tell me who is the Middle mother of Lord Rāma? ,i.e who is younger? Please use references from Vālmīki Rāmāyaṇa.
Thanks.
