How to clean baby's ears? What is the frequency?

i used to clean my baby's ears with the help of a Q-tip. i would just make it a bit damp with water and gently clean the easily visible areas, without really going towards the ear canal. that is an area you should definitely avoid. i did it only once in about 2 or 3 weeks, and it was enough to keep the ears clean. also, i would make sure that for the first 2 years, the doctor checked the ears each time of the visit to make sure there was no wax buildup.
