Nefertiti then follows Smenkhkare as coregent for a time, using the name Ankhkheperure Neferneferuaten. Dodson concludes that Nefertiti was the mother of Tutankhaten, so after Akhenaten dies she continues as regent/coregent to Tutankhaten. Dodson proposes that, in that role, Neferneferuaten helped guide the reformation in the early years of Tutankhaten and conjectures that her turn around is the result of her 'rapid adjustment to political reality'. To support the Nefertiti-Tutankhamun coregency, he cites jar handles found bearing her cartouche and others bearing those of Tutankhaten found in Northern Sinai.
