Kids learn by playing. The more you can make learning to swim fun for your kids, the more they’ll like it, the quicker they’ll learn, and the more fun you’ll have teaching them. You can use toys your kids are familiar with to make learning to get into the pool easier.
Play with boats in the bathtub. Show your kids video of a boat easing down the boat ramp into the water. (Make sure you check it out first. This isn’t a good time for bloopers.) After your kids have practiced getting into the pool, make a game out of pretending to be a boat going down a ramp into the water.
