Picked DS2 up from nursery today & one of the nursery supervisors asked me if I'd noticed him licking things.
I told him I hadn't noticed him doing this, other than licking his fingers.
It appears that he is licking toys, computer screen & even other children at nursery!!
I don't know where he's got this from or why he's doing it.
I feel embarrased that he's doing this, but am not sure exactually how to handle this.
