She’s a hands-on mom! Kim Kardashian had a blast playing around with 3-year-old daughter North and 8-month-old Saint at the pool during their Mexico vacation on Friday, August 19.

The 35-year-old reality star looked white hot in a skimpy one-piece bathing suit that featured major cutouts and flaunted her recent weight loss while hanging out with her kids at Casa Aramara in Punta Mita, Mexico.

Kardashian and North posed for some candid shots of their family fun. The Selfish author swung the tot through the air and twirled her around during their poolside day. North proved she’s already a fashionista and wore an adorable pink two-piece. She also showed off her cute curls, which are usually pulled back into a bun.

The mom of two was all smiles watching North splash around and jump off of pool floats. The 3-year-old even belly flopped into the water as Saint laid on a nearby float.

Kardashian — who shares North and Saint with husband Kanye West — has been showing off her slimmed-down figure in several revealing bathing suits during her getaway. Earlier in the week, she took the kids to the beach wearing a teeny-tiny pink bikini.

The video game mogul has shared the progress of her post-𝑏𝑎𝑏𝑦 slimdown on social media. She’s lost more than 60 pounds thanks to rigorous workouts with her trainer, following the Atkins diet and doing beauty treatments such as the nonsurgical tummy tuck.

“I was motivated, but it was tough!” she wrote in an August 8 blog post of shedding the pounds after welcoming Saint in December. “It isn’t easy to just bounce back. 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.”
