She's fab, isn't she. Thoroughly recommend her book to anyone who hasn't read it. I reread it quite often!
DS2 (not on the spectrum) is the only one of my DSs who pesters for presents. DS1 is happy for us to choose his presents, and DS3 doesn't have the foggiest inkling about Christmas. He does like wrapped presents though, particularly if they are cube/box shaped, and will carry them around happily for weeks.
