My 18 month old son has recently had grommets fitted and we are very happy with the results. However, we are desperate to find a good method of plugging his ears at bathtime without him pulling the various devices straight back out again. So far, ear plugs, cotton wool coated in vaseline, and blutak have all met with the same reponse!
Also, at playgroup the other day, I noticed that a small amount of sand had got into his ear. Is this a cause for concern?
