If you haven't heard of them, you're probably in the same boat that I was before I met DH. They're little holes (just an indent, and I think it's earwax that comes out of it sometimes) right in front of the top part of the ear, where it connects to the face. I didn't think of it being genetic, but apparently it is. DD was born with them, and I'm now wondering whether all of our children will have them. I guess the checklist at birth (checking for all fingers, toes) also has a spot for ear sinuses...
If you have them/ have kids that have them/ know someone that has them, did all or most of the offspring in the family have them? No one else in DH's family has had them... Wierd... I'm also going to post this in the 0-6 & toddler boards, cause I want input! :D Thanks!
