Nightmare repeated

She got gastro, and like Sonny, she went to the hospital and had a heart attack.

Ms Green did not know Airlie had the same condition as Sonny.

Later, tests showed Sonny had the condition too.

'Your house is quiet'

Airlie survived the heart attack, but got gastro again at 18 months and died.

Unfortunately, she got worse.

Before she knew it, they were in the ICU, and nothing could be done.

Ms Green says the pain never goes away.

It hits her that this is her life now.

The kids are not there, and the house is quiet.

Call for change

Ms Green wants genetic testing for all children who die with no known cause.

She says a simple genetic test could make a big difference.

If she had known about genetic testing, she could have made a different choice.
