Too cute for words! Saint West has grown up so much since his first picture debuted via mom Kim Kardashian‘s website on February 22. As seen in new photos of him vacationing with Kardashian at Casa Aramara in Punta Mita, Mexico, he’s reached some new milestones, like sitting up by himself and even tottering on two feet (with the help of mama, of course).
Kardashian, 35, played with North West, 3, and her 8-month-old little boy in the sand and right along the waterline, splashing with them as the tide came in. Saint donned a pair of loose-fitting trunks and flashed big smiles at his mom, who held him close in her arms. Meanwhile, North matched the Keeping Up With the Kardashians star in a rust-colored two-piece.

Kardashian’s coordinating swim style flaunted her newly slimmed-down 120-pound figure in a thong-cut string bikini by Acacia. Her hourglass curves are a testament to her strict diet and exercise routine.
The Selfish author has been transparent about her weight-loss journey since giving birth to Saint back in December. She’s documented her Atkins 40 meals, her vigorous workouts with instructor Dom and even a non-surgical tummy tuck, via Snapchat.
Most importantly, the Kimoji creator wants fans to realize, “it isn’t easy to just bounce back,” as she stated in an August 8 post on her app. “I was so jealous of women who had these cute little baby bellies and would gain 25 pounds — and then, a few weeks after giving birth, somehow look exactly like they did before they were pregnant … That’s not me.”
Which is why she celebrates every inch lost. “See my choker?” she asked in a recent Snap. “Look how big it is. My neck even lost weight!”
