I absolutely love this. I am a swimming teacher and cannot recommend these enough. I have just bought this for personal use for my 26 month old boy - until then I had taken him in the pool without any floatation aids. You must consider the confidence and balance your child has and cannot expect them to go straight in a pool and float. It is to aid swimming - WITH AN ADULT ALONGSIDE. I took out 4 of my son's floats (from the front first and in 2s so its balanced) on his first swim with this to ensure he was in the right position - upright but leaning forwards - you want them to swim, not float!
