Swim Ear are ear drops you can purchase on the internet and are great as a preventative for ear infections, a lot of teachers use them! They work by drying out any risidual water left in the ear after swimming. Ear plugs also work well, but we recomend not to purchase the blue ones because if and when they fall out they are really hard to find against the blue tiles of the swimming pool! Ear plugs also come in a wax form which tend to be more comfortable in the ear and again can be found via the internet. A swimming hat is a good tool to help to keep the ear plugs in place but not essential.
