What to do re. possible OCD traits?

[Plinney]

Teenage DS15 has a few traits, I believe. Am I right or wrong?

Re-washes crockery and cutlery and glasses etc before using.
Uses lots of tissues, kitchen rolls etc (doesn't like using tea towels after 1 use)
Over fussy about food, sell-by dates and so forth.
Opening new milk before finishing old.

Should I just leave him to it and not say anything?

I'm find myself getting cross at wasting food, paper, etc doesn't seem to get anywhere e.g. today we had a row when I said "use iceberg lettuce its absolutely fine", he said "no, there's brown edges", I said "just cut them off!" etc etc etc.

But am I wasting my breath by saying something? It seems so, as nothing changes.

Also, is it counterproductive i.e. could I actually be making it worse by complaining?

I think definitely try to have a conversation about it. It's a really horrible disorder & hard going on the sufferer. It definitely sounds like he is suffering with ocd - it depends on how much his behaviours interfere with his life & whether he wants to do anything about it.
You could tell him that you've noticed that he gets anxious about some things & ask him if its a problem for him. Or do you have a family member who he trusts & who he might confide in?

Hmm...mine is a bit like this (DS, 14) but rather than OCD it's more just sensitivity with him, like he can tell if we got pancakes from a different shop...or if something is cooked slightly differently or very slightly off, quite fussy about some things.

I'd talk to him and find out what he is thinking, first.
