The 33-year-old son of the president took to Instagram on Monday to post four photos of Lara, 35, enjoying their vacation in Florida with their nearly three-month-old son.

Precious: Eric Trump took to Instagram on Monday to share a series of stunning images of his wife Lara and their baby boy Luke 

Look of love: Lara is lovingly gazing at her only child in the first photo that Eric shared 

In the first photo, Lara is lovingly gazing at her only child, while he is staring off into the distance with his little lips puckered. 

Lara shared the snapshot on her own Instagram page to the delight of her husband's former stepmother, Marla Maples, who couldn't resist gushing over the picture. 

'Hello there precious one!! Xoxo,' she wrote. 

The adorable photo also attracted the attention of former Real Housewives of New York City star Jill Zarin, who commented: 'Dying.'  

The next snapshot Eric posted sees Lara lying on the grass with her legs in the air as she uses her feet and hands to lift Luke above her head.

Loves of his life: Eric called Lara and Luke his 'two favorite people' when captioning the images 

The mother-of-one looks relaxed in a white tank top and ripped jeans, while Luke is sporing a light blue Ralph Lauren onesie.

Palm trees are pictured in the background, and the images were presumably taken while the family enjoyed an extended Thanksgiving vacation at President Trump's Mar-a-Lago estate in Palm Beach, Florida. 

The third photo sees Lara striking a more traditional pose with Luke, as she holds him up on a wooden swing while kneeling behind him. 

Lara's emerald-cut diamond engagement ring and wedding band are on full display, and she is also wearing a pair of gold and white bangles on her left wrist.

In the final photo, Lara is lying in the grass again with her head resting on her hand while Luke is sitting against her leg.

Back in shape! Lara posed for photos with Luke, Eric, her friend Emily Aronson, and her parents, Robert and Linda Yunaska, after running a half marathon this weekend 

Lara gave birth to Luke less than three months ago, but she is already back in running shape.   

She ran a half marathon in Palm Beach over the weekend, proudly posing for photos with her husband and their baby boy after completing the 13.1-mile race. 

Lara, who gave birth on September 12, took to Instagam on Sunday to share two photos of herself posed with her family and friends following the lengthy run. 

'Great way to wrap up the weekend — 13.1 miles #PalmBeachesHalfMarathon,' Lara captioned the images, which see her wearing a neon sports bra, a form-fitting gray tank top, black running shorts, and her finishing medal around her neck.

Fit: The mom kept exercising while expecting and sometimes took to social media to share videos of her sessions, including one when she was nearly 10 months pregnant (pictured)

In the first image posted to social media, Lara is holding her 11-week-old son while posing for a photo with Eric, her close friend Emily Aronson, and her parents, Robert and Linda Yunaska.

The next photo sees Eric and Lara are lovingly gazing at their only child, who is wearing a cheeky onesie that reads: 'The last nine months were my off-season.'

While most new moms would scoff at the idea of running such a grueling race after giving birth, Lara seems to have bounced back with ease thanks to the intensive pregnancy workouts she did with her trainer right up until the days before the birth.

Just a week before she welcomed baby Luke, Lara shared a video of herself doing lunges and lifting weights at the gym while 39 weeks pregnant. 

Wild: Lara shared an adorable photo of Luke's hair standing straight up, using the hashtag #Mohawk to caption the snapshot on Saturday 

Reading time: That same day, Eric shared a  picture of Luke sitting on his lap while they read Kat Kronenberg's children's book Dream Big in a lawn chair

Lara told Daily Mail Online in August that she had been 'blessed with an incredibly easy pregnancy' that has allowed her to remain fit and active throughout.

'I was always a little worried, because I had heard different things from different people about their pregnancies; some people have to stay in bed for months... you never know what you're going to get,' she said.

'I knew I needed to workout for my sanity, and I try and make it a daily habit if I can, so I count myself very lucky that I have been able to keep doing that while pregnant.' 

Although doctors recommend that women take some time off from exercising after giving birth, it is suggested that those mothers who have remained active throughout their pregnancies, as Lara did, will be able to return to their regular gym routine fairly quickly after welcoming their child.   

New mom: Lara took her baby son for his first swim over Thanksgiving weekend, making a very fit appearance in a bikini just two months after giving birth

Family time: The new mother took little Luke for a dip inside a swimming pool at Donald Trump's Mar-a-Lago estate in Palm Beach, Florida

That time frame is extended for women who have undergone a C-section; in this case mothers are advised to wait a minimum of six weeks before hitting the gym once again.

For Lara, however, that clearly wasn't an issue; the new mother was up and at 'em soon after giving birth to her first child, sharing images of herself playing golf, riding her beloved horse, and going on hikes with friends in the weeks after welcoming little Luke.

Lara and Eric have been on vacation at the Trump family's Mar-a-Lago resort since Thanksgiving, and the couple has shared plenty of photos of their baby boy enjoying some fun in the sun over the holiday the holiday season. 

On Saturday, Lara shared an adorable photo of Luke's hair standing straight up, using the hashtag #Mohawk to caption the snapshot. 

Adventure: She was excited for the little boy, who was born in September, to wade into the water for the first time, and joked that he 'nailed the backstroke'

Duo: Lara took to Instagram to share two photos of the occasion, showing how she cradled little Luke while exploring the swimming pool with him

Luke's wild hair has inspired many Instagram commenters to say that the little boy undoubtedly inherited his blond locks from his grandfather President Trump.   

That same day, Eric shared the same photo, as well as another picture of Luke sitting on his lap while they read Kat Kronenberg's children's book Dream Big in a lawn chair. 

'Enjoying an afternoon reading with Luke. #DreamBig,' he wrote,

In addition to this being Luke's first Thanksgiving, the little boy also took his very first dip in the pool with the help of his mom last week.

Lara showed off her incredibly trim figure in a bikini as she cradled her baby for his first swimming session at a pool at Mar-a-Lago.  

All together: Lara shared this photo of herself with her husband and baby as well as their two dogs to mark Thanksgiving, saying she was 'grateful for this crew'

And baby makes three: Lara also posted this photo of herself with Luke and husband Eric

The new mom was understandably excited for the little boy to wade into the water for the first time, and she joked that he had 'nailed the backstroke' while sharing images from the swim. 

Lara shared two photos of the occasion, including one showing how she cradled little Luke while exploring the swimming pool with him.

Then, she posted a snap of the baby boy bundled up in a white towel, staying warm after his swimming excursion.

Eric shared two additional snaps on his own Instagram account, with the hashtag #LittleSwimmer. 

Lara and Eric celebrated Thanksgiving along with President Trump, First Lady Melania, and their son Barron at the exclusive estate. Ivanka, her husband Jared Kushner and their children were also thought to have joined the reunion.
