They helped welcome 111 babies.

Kyle Busch helped hundreds of people welcome children into their lives before his tragic death aged 41 last week.

News broke on May 21 that the NASCAR legend had died after a ‘severe illness’. It was later revealed that Busch died from ‘severe pneumonia progressed into sepsis’, his heartbroken family said in a statement.

Busch is survived by his wife Samantha, and their two kids, four-year-old daughter Lennix and 11-year-old son Brexton.

The three of them made their first public appearance since Busch’s untimely death on Sunday at a Coca-Cola 600 pre-ceremony, which the two-time Cup Series winner was due to take part in.

But Busch’s sports record and his family aren’t the only legacies he leaves behind – he will also be remembered by the families of the 111 babies he and Samantha helped fund IVF for.

In 2015 the celebrity couple created the Bundle of Joy Fund and, per its website, over $2.3 million funds have since been granted.

IVF is extremely expensive in the US. The average cost of just one cycle is $23,474, says Carrot Fertility.

With this in mind, the Buschs wanted to help people afford the costs of starting a family.

Why? Because they endured their own fertility issues before welcoming their two kids, with Samantha suffering a miscarriage before Lennix was born.

“Kyle, and I battled infertility for over a decade before being blessed with our two beautiful children, Brexton and Lennix,” Samantha wrote on the Bundle of Joy Fund website.

“Our journey was long and painful – six rounds of IVF, multiple miscarriages, failed cycles, and countless moments of heartbreak. We faced a rollercoaster of hope and devastation that so many families know all too well.

“Through it all, we held onto faith, each other, and the belief that somehow, someday, God would turn our pain into purpose.”
