Sue and Noel teased their happy news via their Instagram account before officially making their announcement via their YouTube channel, The Radford Family.

Their older brother Alfie, the Radfords' 17th child, was sadly stillborn in 2014.
The littlest Radford is also already an aunt or an uncle as the Radfords' two oldest kids are both parents too! Sophie has 7-year-old Daisy, 4-year-old Ayprill and 3-year-old Leo whilst eldest Radford sibling Chris is dad to Maisie-Page, 2, and Jacob, who was born in July 2019.
Let's just hope Noel and Sue haven't run out of baby names! Take a look at the video above for more on the Radfords' happy news - as Sue reveals all about the gender!
