A young mother has shared a heartbreaking video of the final moments she spent with her newborn son before she gave him up for adoption.

Hannah Mongie, 21, was 18 when she fell pregnant unexpectedly with her boyfriend of eight weeks, Kaden Whitney.

But she was "shattered" when Kaden, a church missionary, passed away in his sleep from natural causes two months later.

The pair had already discussed adoption and after Kaden's death, Hannah decided to follow through with it as she believed it would be best for her baby.
