you are in for a future of very particular tastes. lol!
not to say that my kids are spoiled rotten and snobs about what they get, but around the age of 4 or 5, the days of picking of the random7.99 baby doll or whatever game or toy was on the Target 90% off clearance was over.
They had strong ideas of what they liked ( hated bratz, loved myscenes.) hated anything angel or princess. Liked outdoor toys. Loved art kits, didn't care about play-dough.
around 9 or so they started asking for specific music cd's video games, a certain sweatshirt, book, or art supply. When I used to be able to pick up a cheap art kit at the craft store, now they wanted that certain learn to knit set complete with needles and fru-fru yarn.
The first 4 years are the most frugal and affordable you will ever have for christmas gifts. Our first christmas, well.. I didn't buy anything! baby was 6 months old, and grandma sent some presents.
