Is it normal for a three-year old to always have chunks of was coming out his ears (yellowish-red and fairly dry)? It seems like every 3-4 days I have to take another chunk from the entrance. I thought at first that maybe it's a good thing because he will never have his ears plugged by wax, but I have 3 other kids and he's the only one whose ears do that, so I am wondering if it's a sign of some problem?
