For the last year or so my son has been constantly putting things in his mouth. First it was shirt collars and sleeves, to save his clothes we got him silicone chew necklaces but they got irritating as he'd speak with the necklace in his mouth. Then nail biting, now it's chewing skin off his knuckles to the point he removes the whole layer of skin, chewing any scabs he can reach, or chewing the inside of his lips till he draws blood. We still sometimes give him the necklace but not every day.
Teacher has advised getting it checked out. We're looking into occupational therapy (can go private) but just wondering if anyone has any advice/experience/ key things I should bring up.
I was a thumb sucker and nail biter but somehow what he does seems worse as he's hurting himself. In my day no one would have said it was "sensory seeking", just a "habit" (not sure what the difference is to be honest, at some point does the seeking become a habit?) but it seems OT would be addressing potential retained primitive reflexes or sensory processing disorders, all sounds quite serious and drawn out requiring potentially 3-6 months of therapy (he hasn't had the assessment yet).
He seems to be an otherwise "normal" child, very high energy but par for the course at his age.
