Bec Judd has recreated a heartwarming throwback picture featuring her youngest boy Tom.

Posting to her Instagram page, the 41-year-old could be seen enjoying a day at the beach while lying on her back with her son balanced on her knees.

This week during a sun soaked getaway, Bec recreated the five year old photo using the exact same pose.

Tom, now eight, is the youngest of Bec's four children with AFL great Chris Judd, 40.

He is the twin of Darcy, eight. Bec and Chris also share a daughter, Billie, 10 and a son, Oscar, 13.

'Same pic, five years apart, I love you Tom Judd,' the model wrote in the caption.

Followers commented below the image with loving support for the touching mother and son tribute, which Bec posted on Saturday.

'Gorgeous! As if in the blink of an eye they grow... we (hopefully) stay fresh and vital. You are an inspiration,' posted one of the designer's fans.

'Love this my heart,' gushed another follower, while someone else chimed in, 'Adorable.'

Bec likewise posted a photo of husband Chris taking a dip in the surf and added the caption, 'just another day'. 

She also shared a photo in which she can be seen receiving a group hug from her twins Tom and Darcy, which she posted with a blue love heart graphic.

It comes after Bec left her fans worried after sharing a video of her self-tanning routine.

In the video shared to Instagram, the AFL WAG rubs herself down with a mitt while wearing a black bikini.

But it was not Bec's appearance that had them worried, but the fact she was using the famously staining brown lotion in an all-white room.

'Omg tan on the rug and ottoman… lol giving me anxiety too,' wrote one person in the comments.

'That bottle on the cream boucle is killing me inside,' another commented with someone else adding, 'Eeeek the fresh tan near the fresh white giving me chills!'

'Can't believe you are doing this in such a white/cream room! My OCD is kicking wanting to save that boucle chair,' wrote someone else.

However, many were impressed by Bec's skills as the fashion designer didn't stain the area around her at all.

'And you're an expert in tan application…. Not even a drop on the furniture,' said one fan.

'I pretty much give Juddy (husband Chris) the gift guide and send him off with the kids (to get a present) and they can surprise me', she said
