Every parent has been there -- your kid is excited about the season's "it" toy, instantly puts it on his/her wish list and eagerly awaits the holiday. And then just like that, the toy is sold out (or nearly sold out), sometimes just as it hits the store shelves.

When you try to prepare them for the disappointment, they often respond: "Don't worry, Santa will bring it." Well, here are some toys even the big guy is going to have a hard time getting his hands on this holiday season.

"This holiday season has gotten off to an early start with some of this year's stars flying off the shelves already," said Laurie Schacht of The Toy Insider. "With prices under $20, toys like Fingerlings, Pikmi Pops and Cutie Cars are in demand, and while retailers are trying to keep these in stock the demand is higher than the anticipated inventory needed."

So, don't panic -- yet! Retailers are restocking on a daily basis. Even if you don't see a great sale, you might grab them while you can.
