Teng Aai Hong, 36, said she discovered this only by accident.
On Nov 4, Teng caught her daughter tying up and gagging her two-year-old brother with a napkin in their home.
“I scolded her and asked her why she was doing that. She told me that was what her teacher did to her when she was being naughty,” Teng was quoted by The Star as saying during a press conference at Wisma MCA on Tuesday.
Teng said she confronted the headmistress of the kindergarten in Setapak a few days later.
“She admitted to tying up my daughter but claimed that she didn’t do anything wrong as that was her method of disciplining the students. She even went on to demonstrate her method by tying up another student,” Teng was quoted as saying.
Teng claimed her son could have suffocated had she not intervened at the right time on Nov 4, all due to the example set by the headmistress.
According to the report, Teng has removed her daughter from the kindergarten and lodged a police report. Police said they were investigating the matter.
The Star quoted MCA Public Services and Complaints Department chief Michael Chong as saying the headmistress should have known better than to discipline children in this manner. The safety of children was important, he added.
