you pluck the hair from inside the ear to prevent ear infections, If it is not taken care of your baby could suffer from a bad ear infection. It trapes the water inside the ear and can end up being a painful and costly for your little baby. To pluck the hair from inside the ears doesnt really hurt them unless you pull out several at a time, and they come out rather easily. I can get them with my fingers, pull lightly and they come out. It is better to do this instead of wait and chance your baby getting sick, which would you rather a few minutes of inconvience or days of anitbiotics, oral, and ear, and a wash to top it off, trust me, went through it, so not fun!!!
