Floats are great to work on leg technique and kicking, whilst keeping the upper body in a straight position. BECO, HydroKidz, Comfy, Speedo and Zoggs all offer a quality range of children's junior small floats.
A very good, sturdy swim noodle. Would recommend.
Having tried a few different swimming aids the difference this made was immediately noticeable. Perfect amount of buoyancy and my little one was swimming more confidently as soon as she was in the water covering the width of the pool in a fraction of the time it has been taking recently.
