Over the last couple of months, DS1 (6) has started putting his fingers in his mouth a lot. Sometimes he keeps his fingers in his mouth, sometimes he licks his hands, sometimes even licks his arms. It's driving me mad! Telling him not to do it is having no impact whatsoever, except from getting us both nervous... He has some sensory issues and this seems to be a sort of physical need for him. He also had some anxiety issues in the past, although he is pretty relaxed at the moment. I'm pregnant right now, so there may be some anxiety with that.
I really, really want him to stop as I think he's going to get sick and because he'll be going to "big" school in September and I think this could cause some teasing and rejection.
Ideas that I have had are 1) letting him chew gum 2) getting him a boyish necklace to chew instead (gotta be more hygienic than his fingers).
Or, should I just try to chill out and assume that this will pass?
