He fell 15 metres onto a slab of concrete but little Jeremy Tak has lived to tell the tale.
Still shocked and incredulous that his bouncing toddler sustained no permanent injuries from the three-storey fall, Mike Tak said his son has been given a second chance in life.
Two-year-old Jeremy was playing at home with his mother in their Eastwood apartment in Sydney's north west on Monday when he climbed onto a bed in a spare bedroom and pushed on the fly screen covering an open window.
Two plastic clips securing the screen bent open, sending Jeremy and the screen plummeting 15 metres to the ground.
Miraculously, he was left with just a scratch on his right leg.
Doctors at the Children's Hospital at Westmead have examined Jeremy for head, neck and internal injuries but have found nothing. He didn't break a single bone.
Tak, who was working in Newcastle at the time, didn't believe his wife when she called to say Jeremy had fallen out the window but was alive and breathing.
"I had to ask her again whether he was alive," he said.
Jeremy's right leg hit a concrete ledge on the way down, leaving him with a large scratch but possibly slowing his fall. He landed on his right shoulder or arm, his father believes.
Tak's wife was too traumatised to speak about the incident or even go back to the bedroom where it happened but Mr Tak, 39, wanted to speak out to encourage parents to be wary of the dangers in their home.
Just three weeks ago, they spoke about rearranging the furniture in the spare room because Jeremy was growing fast and would soon be able to climb up to the window.
"We sort of delayed it - but whatever is possible to happen, can happen. And in our situation it did happen," he said.
"Children can progress a lot faster than you think and I would tell parents to try to think ahead and make everything in the house safe."
