My son, almost 3 years old loves to swim. He is, however, very uncertain and anxious. With this ring, he feels safe and comfortable. For my daughter, 1,5 years old I have the "red" model. She is the Investigate of the two. And without a ring she would plunge immediately into trouble ... So I can go swimming alone with two and will also meet two. Very good investment. Go swimming at the first time I was however pleased to have this help, because the initial creation is complicated but something. Or earlier practice times at home ...
