Toys are a leading gift for children ages 2-12, according to data from PBM Strategic Insights. In the South, STEM toys, games and puzzles, DIY craft kits and books are big categories for kids on the verge of tween-hood. Last year, L.O.L. Surprise, the gold, dome-shaped toy filled with tiny plastic toys to unwrap, was the big get of the holiday season, as were Fingerlings, the tiny interactive plastic monkeys that attach to fingers. This year, both toys are back with updates along with new toys (and some oldies) in popular categories that toymakers hope will become the season's must-have.
