5 Year Old Always Smelling Hands

I do that all the time. Really, I do. I am also a cuticle biter and a skin picker. I usually can refrain from these things in public, but if I were a kid, I might want my parent to help me drop these habits.

Two ways to help kids drop habits. First is to ignore them and they sometimes just go away. Second, is to gently remind them that they are doing "it" and redirect them. The second can work if they don't even realize that they are doing "it".

She's exploring her environment. I see nothing wrong with smelling her fingers. She's not putting them in her mouth so where's the concern about germs? And at home she's already exposed to all those germs.

A very good way to extinguish behavior is to completely ignore it.

She will outgrow that too.
No worries.

No need to worry. My husband does the same thing :)
