My AC don't like accumulating Stuff so I keep presents to a minimum. A couple of books for the little ones or a good quality wooden toy. Now they're growing older, board games will be on the menu. I took one to the family in America when I went to help out with the new baby just before Christmas, but they said it was enough that I'd flown over (which cost me, of course, a four-figure sum).
DiLs parents are quite generous, but she is an only child. Her 'maiden' aunt is always sending parcels, too. The DGS is too young to think about what things cost, but we are just happy that he really loves all his grandparents and enjoys playing with all of us. There is no animosity between any of us.
The other DiL has a very talented family and I am in awe of the things her carpenter brother and needlewoman aunt have made for the DGDs. Not to be measured in monetary value.
