NO ONE knows why or how it happens, but in 2011 Sudden Infant Death Syndrome claimed the lives of 25 Queensland infants.
After losing her daughter to SIDS five years ago, one Warwick mother is doing her bit to raise funds for the vital research.
"On the second of December 2008 we lost our beautiful baby girl, Charli Rebecca AnnMarie Mason, 11 weeks new, to SIDS," Melissa Laredo told the Daily News.
"It was very sudden and unexpected.
"It changed our lives.
"One of the hardest things we still have to deal with is not knowing why.
"There's no answer for why SIDS occurs, which makes us question every day why?"
Mrs Laredo started her mission to raise money for SIDS research last year.
"I try to help in any way I can. I know it may not be a lot, but I do know every little bit helps with much-needed research," she said.
"I am currently a work-at-home mum, where I make handmade crochet beanies, which I sell on my Facebook page, Bubas N Beanies.'
Every week, Mrs Laredo will post new beanies up for auction for the whole month, to coincide with Red Nose Day on June 28.
If people are interested in an item, they can comment with a bid under the photo, with each bid higher than the one above.
At the end of the week, whoever has the highest bid will receive the beanie in their choice of size with free postage Australia-wide.
All the money raised from the auction will go directly to SIDS and Kids Australia.
