Strange behaviour and many questions

[Guest guest]

My son continuously folds his ear and pulls on it. When I ask him

what's wrong he says it is cold. Often it does feel cold. Could it

be causing him some sort of pain inside?

Secondly, does anyone know if sidewalk chalk is okay? The box is so

beat up I don't know who the manufacturer is to call.

Lastly, in looking into EFA's and cod liver oil. Has there been any

talk of metals in the oil such as mercury? I called the manufacturer

and they said that they were well below the whoever guidelines for

that kind of stuff, but just wondering if I want to even expose my

son to that. Is there an alternative oil?

Thanks for any and all help!
