It's Saturday afternoon, and your kid is all excited about the birthday sleepover at which you are about to drop them off. (Admit it: For other reasons, you're a little excited, too.) Despite having the invite stuck on the fridge for two weeks, you suddenly realize that you have nothing to bring in the way of a gift. Problem? No problem, because you remember the Kid's Center, which has a cornucopia of all things that kids like. Books, crafts, science, hands-on stuff, outdoor stuff, puzzles, music, fantasy, stuffed animals, games ... it's seemingly endless. You can shop by category, age, interest or brand—all of it ready to be gift-wrapped at the drop of a debit card. With the perfect present secured, you are the hero-parent once again.
