My triplet boys started learning to swim at home in the bath tub and on a mattress at 2-12 months. At 14 months they played like floating turtles in the deep diving well. At 2 1/2 yrs.old they all went off the 3m board.
Parents you can teach your children to swim using my methods and cues in the Teach Yourself to Swim Like a Pro In One Minute Steps system. And the best part is you can start at home without a pool.
Then if you can find an experienced instructor you’ll all get more value from your lessons because you’ll have mastered the basic skills at home first.
