David, he is just turning two. I doubt he will take stock of who
gives him what. Besides, there will be a bunch of people there
shoving gifts his way - one more or less would not be noticed.
but in later years, if he discovers the gift, it will not gall him,
if u applied a different label to it; something that does not
refer to his birthday, so that it did not amount to an extorted
gift from him, in which he had no say.
Future hurt feelings can be avoided
simply by calling the gift something else,
or calling it nothing, so long as his birthday is not implicated.
