No, you haven't done anything wrong. We've done the same thing. Phillip got given the Rufus bear at dxd. Until recently every year we celebrated Rufus's birthday with a dinner Phillip chose. It was Phillip's decision to do it, and every year I'd ask him if he wanted to. We've only stopped now because Phillip at 13 is too old for teddys. We've also donated toys to the children's ward every anniversary too. This year was his five year anniversary so we took some chocolates to the clinic he goes to instead. I see it as marking another year of managing this stupid disease.
