My dad didn't want to give our sons stuff either. When they were 0-6, he bought them good-old fashioned US savings bonds (big denominations). After that, he just reverted to cash. I love my dad who, like my wonderful late mom, is mustachian.
Dad's actions are especially helpful to counteract the in-laws, who have bought mountains of crap for every occasion for years. My one sister faces the same avalanche of crap for her kids from her husband's side of the family. Which is why she and I eliminated cousin gifts -- having eliminated our sibling gifts many years ago.
