It was not an unusual event in the great scheme of things, but there had been a time when she had simply had to face the terrible reality that they could lose him.
"We were not sure which way this was going to go - there was a point when at times I would think, 'Oh God, this little kid might not be around'."
The diagnosis came as the result of blood tests taken after the toddler had begun to limp, and then stopped walking altogether.
An ultrasound and x-rays showed nothing - but the blood tests did.
Within 24 hours she and her husband were with Toby in an air ambulance on the way to Auckland's Starship Hospital. It would be the first of many visits.
Mrs Condin has kept all the hospital notes and all the special beads of courage young cancer patients receive every time they undergo treatment in hospital.
She had a count-up and Toby's beads showed he spent 55 nights in hospital, between Starship and Hawke's Bay, over three-and-a-half years. The longest stint was just over three weeks in Starship.
There were many times Toby was parted from his big brother, Sam, as Sam would stay with his grandparents while Mum and Dad and his little brother made another journey north. "That was tough on Sam because he was only 5 and had just started school."
The first stay at Starship was nearly a month as the treatment programme was put in place and gradually stepped up.
"You're just not sure which way it's all going to go," Mrs Condin said.
But she said Toby took it in his stride - his only confession of not being comfortable being that he felt "yuck".
To add to the youngster's woes a play on the trampoline with big brother ended with big brother tumbling on top of him and breaking his femur. So, a cast went on and he was even more immobilised.
"The treatment had to go on so he was going to Starship with this big cast on his leg."
He was not yet 3.
In the fight against leukaemia there were nightly jabs and monthly intravenous treatments.
Every third month he would be returned to Starship for an extra shot of chemotherapy directly into his spine under general anaesthetic.
"He was so good - he just did it."
It was a long road to recovery. However, despite having effectively been placed in remission 18 months ago he has to undergo blood tests every three months for the next three years to ensure his body remains clear.
"It's so good to see him now just doing normal things like kids do after having been so sick for so long."
Toby has taken it all in his stride.
"Oh I've had cancer," is how he simply sums up his more than three-year fight.
Mrs Condin said he started at Taradale Primary about 18 months ago, around the time the treatment schedule wrapped up, and he was able to enjoy "kids stuff".
He could not do that for a time as his immune system was weakened and he was unable to fight off the slightest of bugs - with illnesses like measles and chicken pox potentially deadly.
So when some of his mates started getting interested in playing 6th grade Rippa Rugby he was able to put his hand up and ask Mum and Dad if he could have a go.
Two years ago ... no way.
Today ... he's scoring tries and looking forward to his seventh birthday coming up.
Mrs Condin said the support the family had received through Hawke's Bay Hospital, Starship, the Child Cancer Foundation and Ronald McDonald House had been exceptional.
"At times like that it's all about support."
The family's links with Child Cancer remain strong and they continue to stay in touch and be part of the events staged.
"It is something I never thought we would go through."
