Factory workers Kirsty and Kyle Morgan were devastated when they were unable to conceive after three years of trying.
When their only round of NHS-funded IVF failed, they were forced to raise funds themselves.
The determined couple, from Hereford, took to the car boot circuit in their Renault Megane.
After taking part in 75 sales in just six months they managed to raise enough for a second round of treatment.
They flew to Athens in Greece on September 15 last year and seven days later they discovered Kirsty, 27, was pregnant.
The couple welcomed their new bundle of joy into the world on May 3 after Kirsty gave birth to a healthy 5lb 6oz baby boy by caesarean section at Hereford’s County Hospital.

Announcing the birth of their car-boot baby, proud dad Kyle, 32, wrote on Facebook: “Well I am overjoyed to announce that me and Kirsty have had a beautiful baby boy he is amazing he is 5lb 6oz he arrived at 7.40am but not before he gave us one last scare.
“Brought Kirsty down this morn at 6.10am as she was cramping all night and being sick so they measured baby heart rate and that was fine then the doc came down and examined Kirsty and she was still closed so he did an ultrasound and babies heart rate had dropped so the doc said Kirsty had to have an emergency c section straight away so Kirsty was put to sleep.
“But baby and mummy are doing fine now and we are both over joyed but still need to settle on a name xxxxxx.”
The couple have since decided to name their newborn son Alyus James Morgan, who arrived four weeks early.
Kyle, 32, said: “We would get up at 6am on the weekend in time for the 7.30am car boot.
“We would finish there, come home, restock and go back out to the 12.30pm car boot.
“Our weekends were very hectic and we would even do bank holiday car boot sales too.
“In total, we raised £4,900 from the car boots, as well as themed nights including cabaret and bingo.
“Around £3,000 of the total raised was from the car boot sales.
“We sold hundreds and hundreds of items. It spiralled out of control.”

The couple, who have been married for four years, had one free round of IVF treatment on the NHS but it failed.
The couple were dealt a further blow when doctors told Kyle that he was unlikely to be able to father a child naturally.
But the determined couple refused to be put off and turned to car-boot sales to fund a second round of IVF available in Greece, where the treatment is cheaper.
The treatment used Kyle’s sperm so his son is biologically his.

Kyle added: “We were very shocked and overjoyed when the treatment worked.
“We were devastated when the first attempt failed, but the treatment was cheaper in Greece so we tried our luck and it worked.”
The couple won over the hearts of the nation when they started their car boot baby challenge last year.
Kirsty, 27, said: “We went to car boots every weekend, sometimes we did two or three in a weekend.
“At car boot sales items sell for tiny amounts so we knew it would take a long time.
“It’s been a lot of hard work. Doing the car boot sales felt like we were earning it.”

After their first sale in February last year, strangers listened to their appeal on Facebook and started to donate items for them to sell.
And they have vowed to carry on with their fundraising to help other couples who are struggling to have a family.
Kirsty added: “We will be working to help another couple. Over the winter we will do jumble sales and then we’ll do car boots when they restart in the spring.
“We want to fundraise for them too as there’s nothing out there for people with infertility problems.”
