Victims may not talk about trauma
Dr Carol Balhetchet, senior director of youth services at the Singapore Children's Society, said it would be traumatic for children after an encounter with a flasher.
Some may never tell their parents about it - to their detriment.
She said: "It's traumatic for them as it is an unexpected event during a normal routine.
"It would be best if they are able to talk to their parents or a trusted adult about it, but many stay silent.
"With a mature parent to help them through the coping process, the child can deal with the situation healthily."
If they keep it to themselves, they will develop a vicious circle of self-blame after playing it through their heads over and over again, said Dr Balhetchet.
"They might think to themselves, 'I must have done something wrong to deserve this' and put the blame on themselves."
She said that in extreme cases, the child might show symptoms of trauma, such as withdrawing socially.
