Fans of the family seem to approve of the name, with lots of sweet comments appearing on Joolsโ€™ photo.

Yep, the Olivers are certainly known for sticking to a theme when it comes to naming their children.

Chef Jamie, 41, and wife of 16 years Jools have always gone with nature-inspired monikers for their kids Poppy, 14, Daisy, 13, Petal, 7, and Buddy, 5.

At the time of the new arrivalโ€™s birth both Jamie and Jools, 41, said that they didnโ€™t yet have a name for the tot but Jamie had previously hinted in an interview in July that theyโ€™d continue with the natural theme.

โ€˜I think you can guarantee something floral or from the natural world,โ€™ he told OK! magazine last month. โ€˜We might go with seasons this time – itโ€™s going to be a little bit hippy, whatever happens.

โ€˜Iโ€™ll pretend to have a say in the name, but I really have no say.โ€™

Since his entrance into the world the little lad has popped up in some adorable Instagram pictures posted by his mum and dad Jamie even briefly took over Jools’ account to share a beautiful shot of mama and baby snoozing together.

‘bless them both sleeping and exhausted together I can’t tell you what a wicked mum this chick is,’ a proud Jamie wrote.

Awww – welcome to the world River!
