Jenny71, you seem very angry. What unbelievable personal attacks on me, someone who loves children and parents. I wonder how well you actually know me. Obviously, not well at all. I have worked with children and families for 30 years in education and swimming and have had great relationships with them. 1. What do you mean when you say ""fake promises""? 2. How would you know if PSS is inferior and outdated or not? Did a competitor tell you that? If so, you really need to do your research on child development, education and swimming. You need to read our testimonials page on our website. PSS has taught thousands of children safety skills and how to swim. 3. What are your credentials as an educator in swimming? 4. What compromise did you ask for? 5. ""Children will suffer for seven years"", what do you mean by that? 6. How many sessions did you attend Potomac Swim School? 7. All private swim schools, that have their own pools, around the world have warm water. Research shows, in the laws of physics, that warm water allows people who are learning to swim to have warm muscles, so that they can move and it is safe for them. When learning to swim an expert does not want people or children in water that is cold, it can be dangerous. Our Waterbaby parents and infants shiver if the water is 85 degrees.
