Ear Band-it has saved us from numerous ear problems! My son has had tubes in his ears for the past year - he is three and a half now and this is an essential to any bathtub, shower, or pool time!
It completely cover the ear and is so easy to use! It is easily wrapped around the childs head - to ensure that no water gets in. It really works too!
The kids love it, they know that it is essential to stop any ear pain and like the colors available. The fabric is soft and easily applied to the head with a strap and stays secure throughout! It can be difficult to use this while trying to wash the child's hair - but as long as you are careful than it is a task that becomes completely doable. Using it a little lower than usual can ease the process.
