Children definitely do get ptsd. We've never been properly diagnosed as have no insurance; but I'm pretty sure I have it from our fire, and I see my son being the same way. He's worried about everything now and gets upset a lot about things that you wouldn't think would upset him. Of course I get the blame for it - my husband and mom both say he's "feeding off me" and he's just acting that way because he sees me when I get upset.
