UPDATE: THE parents of a young boy tragically killed after being hit by a garbage truck are "tremendously grateful" for the support shown by the Toowoomba community.

Olivia Atkinson gave birth to their second son Isaac less than 12 hours after their 22-month-old Lochlain died.

Mrs Atkinson's uncle Denver Vidler said that the response to their situation had been overwhelming for the couple.

"The responses coming in through The Chronicle Facebook page…even though Paul and Olivia are really struggling, they're touched that people actually care and are sympathetic towards their situation," he said.

"There are a lot of parents out there who have experienced similar tragedies and really connect with it all.

"This is where Toowoomba's always had that special community feel - it's certainly a special community up that way, that's for sure."

A Facebook page Lochlain Forever has also been set-up by the community.

The couple own the The Original California Burrito Company in Grand Central Shopping Centre, and had to shut down the shop for several days.

Mr Vidler said the Atkinson's were in need of financial support associated with funeral costs and keeping their business running.

Lifeline Darling Downs will accept donations on behalf of the family to cover funeral costs.

Cash and cheque donations can be made at 33 Russell St in business hours, and cheques can be mailed to PO Box 2119, Toowoomba 4350.

To donate by direct deposit, transfer money to account name: Lifeline Darling Downs, BSB 034 221 and account number 581 625 with the name Atkinson as a reference.

SATURDAY: THE mother of the 22-month-old toddler tragically killed at Kleinton has given birth to a baby boy who will never know his brother.

Olivia Atkinson, 22, went into labour only hours after her first son, Lochlain Atkinson, was hit by a garbage truck and killed outside the family's Charmaine Ct home.

The shock of the tragic and freak accident sent her into early labour.

In the early hours of yesterday Friday morning, with her husband Paul by her side, Olivia gave birth to a healthy baby boy they have named Isaac.

He will grow up not knowing his brother, who has been described by his great-uncle Denver Vidler as a "gorgeous kid" who was always "content".

"He was such an important part of what is a strong family unit," Mr Vidler said.

"He was a beautiful little kid who loved pushing his little trolley around.

"He loved his gumboots and his mini camping chair.

"He was just a happy chappy."

Mr and Mrs Atkinson moved to Toowoomba in March this year with Olivia's parents Ken and Davina Vidler.

The family moved after a series of bad breaks.

They struck financial trouble a few years ago and soon after Ken was diagnosed with multiple sclerosis.

In an attempt to find their feet again, the family moved to Toowoomba and opened The Original California Burrito Company in Grand Central Shopping Centre.

"They were trying to follow their new hopes and dreams.

"And they really loved this area. Then this ..." Mr Vidler said.

Mrs Atkinson is today recovering in Toowoomba Hospital after complications related to the birth of Isaac.

Mr Vidler said the "strong family unit" was working together in an attempt to get through such a devastating and conflicting time.

"It's such a bittersweet situation," he said.

"They're dealing with what has happened and at the same time coping with the arrival of a new baby.

"Paul ... he just feels ... I suppose surreal.

"What do you do? How do you feel?"

Mr Vidler described the incident as a "freak accident" and said the family held no ill feelings towards the garbage truck driver.

He said the family desperately needed help to cover the costs of the funeral and those associated with keeping the Grand Central business operational.
