Generally, in the Orthodox Christian tradition, icons of the Theotokos show her holding her Son, our Lord Jesus Christ. She is the Mother of God, and so it is right to represent her as a Mother holding the infant Jesus Who is God.
St. Christina - July 24 Your lamb Christina, O Jesus, Calls out to You in a loud voice: I love You, O my bridegroom, And in seeking You, I endure suffering. In Baptism I was crucified so that I might reign in You, And died so that I might live with You. Accept me as a pure sacrifice, For I have offered myself in love. By her prayers save our souls, since You are merciful.
