"The baby was put off the ventilator as the chest infection had cleared and the blood infection had also subsided. But she developed some difficulty in breathing Saturday and had to be put back on it," said Deepak Agrawal, assistant professor of neurosurgery at the AIIMS trauma centre.
Falak was brought to AIIMS by a teenager Jan 18 with a fractured skull, bruises and human bite marks all over her tiny frame. The girl who claimed to be her mother is now in a juvenile home. Nine people, including key-accused Raj Kumar Gupta who had handed over the baby to the juvenile, have been arrested in the case.
The police probe delves into human trafficking and prostitution angle.
The team of doctors monitoring the toddler's condition had said the chest and blood infection have subsided, but the brain infection is still a cause for concern.
Her condition had shown "marginal improvement", according to doctors.
The baby has undergone three surgeries so far. Doctors say the baby is stable, but critical.
"She continues to be critical, but stable," said Agrawal.
