The model mama shared a clip of her baby girl showing off her skills in the water

Coco Rocha‘s 16-month-old daughter Ioni proves she’s a total natural in the water while learning how to swim.

The model, 27, posted a video of her husband, James Conran, teaching their daughter to swim with pink princess floaties while vacationing in St. Tropez for their friends’ anniversary.

“Daddy teaching baby to swim in St. Tropez,” Rocha captioned the clip on Instagram.

Ioni nailed the breast stroke and stays afloat with Dad nearby, while Rocha cheered from the sidelines.

Prior to the swim sesh, the jet-setting baby also looked adorable in a striped dress while the couple took to sea.

Rocha has been hitting many milestones with her mini-me, saying they were also trying to potty train Ioni at 13 months.

“Although I am being told that it is very young, I think we’re going to do it,” Rocha told PEOPLE in May.

“I think we can do it. I think the funny thing is that throughout her one year of life, you really don’t get to teach them anything. This is the first time I’m literally teaching her something — so we’ll see if we’re successful.”
