...its deftly a "thing" with him... I hope he grows out of it. I explained to him that what he is feeling is normal but needs to be done in the privacy of his room or shower...can't believe I had to explain that to a 4 year Old.
Feet are weird things. They're like hands, but not. They have strange little wiggly worm toes. How can he not be curious about them? I mean, take some time and play with his feet. When you're learning about the world even the littlest things us adults don't think twice about are such mysteries.
I doubt it's a foot fetish, just something new for him to explore.
I agree with rose it sound like he's going through a phase and possibly has a foot fetish. I wouldn't think too much of it as kids that age are constantly learning and evolving.
Sounds to me like he already has one. ;D
There are worse things in life than guys who love feet.
