Let the day job know they can kiss both sides of my ass. Let Mom and Dad know they're set for life - you'll see X amount deposited in your account each month, spend or save how you see fit. Same for wife's folks.

Other family, close or distant "You should hear it from me, you get nothing for nothing. Don't make it weird for both of us by asking. If this upsets you speak up, you can be culled from the Christmas card list post haste if thats how you want it to be".
