Ms Smith and her husband Ben Soffa announced the birth today, Wednesday July 11.
She said: “Absolutely thrilled to welcome Elijah (know as Eli) to the family.
“We’re now all back home and settling in to all of life’s new challenges.
“He’s a bit longer and heavier than we’d imagined from the bump (3.6kg / 8lbs) but we’re loving every last bit of him.
“Thank you to all the brilliant staff at the Royal Lancaster Infirmary who brought him into the world safely.
“Thank you Ben for being a great support throughout the journey.”
