Maralee Nichols is in a sunset state of mind.

Over the weekend, the model and her son Theo Thompson enjoyed some peace and quiet at a neighborhood beach. In photos shared on Instagram, Maralee and her 16-month-old, who she shares with Tristan Thomson, took in the sunset before frolicking in the sand.

"Happiness," she shared April 2. "It's the simple things in life that are the most extraordinary."

While Maralee and her growing baby boy had some fun in the sun, Khloe Kardashian and Tristan's daughter True Thompson was treated to an early birthday party.

On April 1, Khloe thew an Octonauts-themed party for her daughter complete with ball pits, piñatas, desserts and undersea creatures. "Her birthday isn't until April 12th, but we decided to celebrate it yesterday," Khloe wrote on Instagram Stories April 2. "True is obsessed with Octonauts so we had a pastel/Octonaut extravaganza."

Tristan, who also shares an 8-month-old son with Khloe, was not seen in photos from the bash.

While the status of Tristan and Maralee's relationship is unclear, she continues to give glimpses of her life as a mom, including trips to the pumpkin patch and footage of Theo's first birthday celebration.

"Spending the past 365 days with you have been the best days of my life," she wrote in December. "You are my greatest blessing, my world, my heart in human form."
