Keeping track of the best selling Christmas toys can seem like an uphill battle. Just when you feel like you know exactly what your child wants, a new toy is advertised on a new commercial. Saturday morning cartoons in the months before Christmas seems like an endless day of "I want".

Believe it or not, there are some toys that stand the test of time and maintain their position in the top 10 best selling toys. The list does fluctuate, but these gifts seem to remain on top:

1. Zhu Zhu Pets Hamsters. These are red hot for Christmas 2009. These have already become the best selling Christmas toys for 2009 as they are sold out in a lot of locations. Zhu Zhu Hamsters are hot and have a lot of accessories to make playtime extra fun. The Funhouse seems to be the most wanted accessory.
2. Transformers. These are very popular for boys right now. More specifically, Transformers Revenge of the Fallen toys.
3. Live Butterfly Garden. Kids can watch a butterfly grow all the way from larvae. Very fun and educational.
4. Bananagrams. A word game in a cute banana pouch.
5. Mindflex. We had nothing like this when I was growing up! You have got to check this out!
6. Anything Twilight. Twilight is huge this year. From 10 years on up, everyone seems to love Twilight.

Although the best selling Christmas toys list seems to fluctuate, these remain hot items. Shop early and shop safe with a retailer you are familiar with.
