I do, especially after my youngest son was born. I come from a thin lipped family, my husband has thin lips, but my son has very full lips. I have not yet figured out, where they come from. Frequently I study old family photos, looking for someone with full lips, haven't found them yet. I don't mention it to him, I don't want him wondering if I have lost my mind, (he already knows I have). He and my older son both have my father's eyes. One of my aunts always says, as long as my oldest son is alive, my father lives on -he favors him a lot. But I also look at features on other people, one is the area between the nose and mouth -the mustache area, take a mental survey, some people have a wide area -major mustache, some have a narrow space, thin mustache.
I have been saving these pictures, I hope to do an art project with them at some point, but they seem to have fuller lips, especially one in particular!
