'The cutest little sidekick': Jools Oliver posts sweet snap of daughter Petal Blossom, 6, bathing newborn son River Rocket

She gave birth to baby River Rocket Oliver less than a month ago.

And besotted mother Jools Oliver, 41, shared another adorable snap of her newborn son with celebrity chef Jamie, 41, as he was bathed by the couple's youngest daughter, Petal Blossom, six. 

Taking to Instagram on Friday, the doting mum-of-five, looked on proudly as her little girl gave a helping hand at bath time. 

Jools wrote alongside the sweet snap: 'I have the cutest little sidekick'.

The brunette and husband Jamie - who also raise daughters Poppy Honey 14, and Daisy Boo, 12, and son Buddy Bear, five, together - have posted numerous snaps of their latest arrival on social media over the past month.  

Last week, Jools captured the angelic newborn in his Moses basket, with the caption: 'Oh, little River.'  

In another snap, protective big sister Petal cradled the tiny tot in her arms while posing for the camera.  

Another shot was posted by her cheeky hubby, who joked he had 'hacked' Jools' account, showcasing both mother and baby fast asleep. 

But rest assured, Jamie wrote a gushing caption praising his wife for being a 'wicked mum'.  

It was via Instagram that Jools originally dropped a major hint about the baby's name.

The couple confirmed speculation as they shared a photo with the words 'Dream big River'.
