Tim and Angela Black have shared their heartbreak for the preventable loss of their son Lachlan, in the hope more parents will follow their intuition.
Two-year-old Lachlan Black died after being seen by five doctors in four days and going without the antibiotics he desperately needed.
When Lachlan came down with a fever and a rash, the parents took him straight to the hospital.
Speaking to 7 News in Australia, the couple said they visited the hospital three times and saw two separate GPs.
"Even more than that really, because there were multiple doctors involved in his care," the mother told 7 News.
No one seemed to figure out what was wrong with the toddler.
"He just got worse and worse and unfortunately no one seemed to clue it wasn't a virus," the dad said.
Lachlan died in intensive care from a streptococcal infection.
"Eventually the doctors came and told us he had died, and we spent that night holding him."
The grieving mum says her boy died a "third-world death in a first-world country".
The couple is now warning other parents to "trust your instincts".
"Act soon and act first, worry about people's opinions later; the other way the price is too high," the dad said.
