I have a four year old just completeing her first year of swim lessons at Emler. They teach more than swimming and I don't think you can find a better place for them to learn water safety. She can swim 10 seconds underwater to her teacher. I was somehow under the impression that once she could swim, I would be totally confident about her abilities, but it is an ongoing thing when they are young and they can quickly forget what they have been taught if you drop out for the summer like we did. Bottom line, I would do it all over again especially knowing the statistics on children's mishaps with water.
