DS2, 4 months, has a fabric fetish. He happily wraps any fabric around his fist, and then chews on it. It's a bit weird to me, but it keeps him happy.
I'm sure other people's kids had, or have, this sort of fetish. Did they end up with a comfort blanket? Or did they just leave wet spots on everyone's clothes? When did they grow out of it, if they ever did?
