Little Lacy Angela McElhinney was born in Glasgow's Southern General Hospital at 12.16am.

The hospital said both mum and baby were doing well.
A spokeswoman from the hospital said: "She was delighted.
"It was a straightforward birth. Mum went home to enjoy the rest of Christmas Day with her newborn."
Proud parents across the country were celebrating the arrival of Scotland's Christmas babies today.
Hot on Lacy's heels was another girl, Lucy Thirtle, who was born in Ayrshire Maternity Unit, at Cross-house hospital, Kilmarnock, at 12.55am and weighed in at 6lb 1.5oz.
She is a proud addition to the family for her mother Jacqueline Clark, from Dalmellington, where she lives with partner Shaun Thirtle and Lucy's 16-year-old brother Dylan.

She was finally induced on Christmas Eve and he arrived in the early hours of December 25, weighing 8lb 1oz.
