Psychologist Dr Meriam Omar Din said further investigations and checks were needed to identify the real cause behind such a cruel and inhumane act.

“There are many factors that could have triggered the action.

“As such, parents are advised to be more sensitive and cautious in selecting child care centres and babysitters to avoid any untoward incident.”

The boy was reported missing on that day before his body was found placed in a green zipper bag inside the freezer compartment of the fridge at the house by the police, late at night.

Former Universiti Kebangsaan Malaysia lecturer Prof Dr Rohaty Mohd Majzub said every babysitter working at child care centres should undergo special tests, including the personality and psychological aspects, to avoid a recurrence.

“Children are a trust from God, do sacrifice in raising them. Make sure child care centres are regularly monitored.

“Parents should not leave the responsibility of taking care of their children solely to babysitters,” she said.

Meanwhile, Persatuan Komuniti Prihatin Setempat secretary Kamal Ahmad Abdullah said such an act was beyond the norms of humanity, and that proper guidance should be provided to any person who wishes to offer child care services.

“Parents who intend to send their children to such centres are advised to do background checks on the babysitters and the environment at the centres beforehand.

“Do look for registered babysitters or centres which are supervised by the authorities. As for the pay, it is okay if it is a bit expensive as long as security is guaranteed,” he said.

Pertubuhan Wanita Dalam Perniagaan dan Pemikiran Kreatif (Pewangi) president Nabila Sanusi said such a tragic incident was not the first negligence case to have occurred at homes of babysitters.
