TV cook and author Donal Skehan has revealed the name of his new bundle of joy while thanking fans for their sweet messages.

The presenter took to social media last weekend to reveal he and his wife Sofie had welcomed their second child together, another baby boy, joining their first son Noah, who turns two next month.

He has now posted a new picture of their newborn son on Instagram and announced his name - Oliver Kai Skehan.

He wrote in the caption: "Hello baby Oliver! This time last week little Ollie arrived into our world and we've been smitten ever since.

"Taking time to soak it all in and enjoying every minute! Settling in to life as parents of two has had plenty of ups and downs but wrapping up week one with a smile.

"Oliver Kai Skehan, I hope you're ready for the fun! Thanks for all the sweet messages."

Announcing their newborn's arrival last weekend, Skehan posted a photo of Sofie holding their son wrapped in a blanket.

"Welcome to the world little guy, what a whirlwind the last 36 hours have been," he wrote.

"Sofie Skehan and baby boy doing great give or take a little less sleep, he is a bouncing little bruiser weighing in at 9 pounds and looks just like his big brother. Arrived late on Thursday night after a walk and a steak dinner!

"Thank you to all the brilliant nurses and our doctor who dropped their Thanksgiving plans to bring this little dude into our lives! All exhausted here but grateful to be back home safe and sound with our new little addition."
