A source in the Investigative committee told TASS: 'She waited until the parents with the elder child left the flat, then for unknown reason she killed the child, set fire to the apartment and left the scene.
'She was detained at the metro station Oktyabrskoe Pole.'
The dead girl, who is said to have had learning difficulties and could not walk. Her family, from the Oryol region, was renting the apartment.
She suffered damage because of birth problems in August 2011.
The family took her for treatment to China - and were saving money to travel for subsequent care in Germany.
The parents told police the nanny had been working for them for 18 months.
Sources say the babysitter told interrogators she did not want to hide from police, and aimed to draw maximum attention to what she has done.
She had not intended to ignite the flat deliberately and destroy evidence, she said, according to the source, and wanted the parents to know who had killed their daughter.
The woman had a valid residency permit for Russia but was working illegally. She had no work permit, said officials.
The nanny faces up to 20 years in jail if she is deemed psychologically fit to stand trial.
This afternoon, the investigation was taken over by the FSB, Russia's powerful domestic secret service, once headed by Vladimir Putin. Police are not currently treating the incident as terrorism.

LifeNews claimed: 'Investigators suspect that Gulchekhra had manic psychosis developing for a period of time.'
A law enforcement source said the woman was suspected of handling 'explosive elements' at the flat which was engulfed in flames.

The security services are hunting for the woman's husband. A source said she may have been on 'light drugs'.
Russia's children's rights commissioner Pavel Astakhov called the killing 'Monstrous and inexplicable', urging parents to carefully check on the mental state of nannies when they are hired.
