SINGAPORE - A 35-year-old woman was arrested on Thursday (Dec 29) after parents complained that their babies became listless after she babysat them.

Mr Tan, who asked that his family members' names not be revealed, told The Straits Times that his 11-month-old daughter is still in hospital after spending eight hours at the nanny's home in Hougang on Christmas night.

They did not normally engage a nanny, but had an emergency to attend to that night, he said. They found the nanny, who claimed to be a former nurse, through a Facebook group for mothers. She charged them $30.

His wife said that when they dropped their daughter off at the flat, the nanny looked "decent" and assured them that she would take good care of the toddler.

But when they went to pick their daughter up the next morning at 6am, the usually active child was drowsy and her eyes were half-closed, Mr Tan said.

"She looked drugged, was cranky and couldn't sit straight."

Even a nap, his daughter still appeared drowsy and could not control her limbs. The Straits Times understands that at least two police reports were made against the nanny.

Mr Tan said that his daughter seemed better but was "still not coping well" and will be hospitalised until next week.

During the arrest, police took away medicines from the nanny's home including cough mixture, Shin Min Daily News reported.

Police said investigations are ongoing.
