This is such a strange question.
DD just turned 5. Cold season is here, which means we once again get to see her licking her runny nose. Not below her nose, but the whole way around the nostrils. Kind of like a dog. It's pretty disgusting. I've never seen DS, 3-1/2, do this. Little kids are proportioned so differently, and I don't know if this ability is just something she'll grow out of or something she'll have to learn to stop doing. We have tissue boxes all over the house and she knows how to use them, but it's obviously so much easier for her to lick her nose clean. I hate to make a big deal of it because then she'll do it to get attention or irk us. Now, luckily, it's just to get her nose clean. Do any of your kids do this?
ETA Oh, I see you wrote that already!
Anyway, he is a teenager now and can still do it but he never really does, only when we joke about it in the family, I don't think he ever does around his friends.
If she's in school, maybe telling her that it's not a good idea in public but that she can do it at home would help. Then hopefully she would develop the habit of just using a tissue, she could keep on in her pocket to remind her. Or even a soft cloth because it wouldn't be as scratchy compared to her tongue.
I think my nephew just stopped doing it, we never made a big deal about it when he was little, we just ignored it and I think that your doing that is a good approach.
That would probably look kind of gross.
I think it's just one of those variations in proportion. I couldn't reach my nose with my tongue like that if my life depended on it. DH could, though - he has a really long tongue. Your nephew may just have a longer than average tongue. I've certainly met a few kids who would totally do that if their tongues were long enough (includeing ds2, so I'm glad his tongue is short).
