Cold water swimmers

When we came back from Spain the girls did not want to go in our pool. All I heard was, "It's toooooo cold mommyyyyy!" They were too spoiled from the water in Spain. Not only was the air temperature in the 80's everyday but the pool water was about 82 degrees. I thought, "have I ruined my girls for cool water swimming?".As the summer went on they finally accepted the cool water of our pool and really started to enjoy it. Our pool temperature hit a high of 71 degrees (21 celsius) but for the most part it hovered around 70. Unfortunately this summer was not that hot and our pool is in the shade from about 11-2 everyday so even with the solar cover there was really no warming to be had. One night we forgot to put the solar cover on and the temperature fell to 68 degrees but when the girls jumped in and I asked, "Is it cold?" they quickly responded with, "NO!". I was surprised but very pleased since I grew up swimming in water that was not warm and I would like my girls to enjoy the same expereince. Today I am confident I did not ruined the cold water swimming expereince for my children. On the way home from school they asked if they could go in the pool. I said yes but figured they would hop in and get out immediately. Ali in the end didn't go in b/c having her clothes off outside made her chilly but Sofia jumped right in. She did get out right away but only so she could jump back in and play around. I really was shocked since the pool was only 65 degrees (18 celsius)! She was probably only in for 5-10 minutes but I guess I can finally say bye to my girls who only swim in the warm waters of Spain.
