From feeling nervous around the water to putting their face in and blowing bubbles! 🫧 Swim lessons can feel a little spooky at first 👻 but with the right support, confidence can grow one splash at a time.

Those ribbons you see Big Blue swimmers get during lessons? They're not just for show - swimmers earn a ribbon every time they level up, and nothing makes us happier than getting to celebrate those moments with them. 💙
