I love signing with my toddler using the Baby Signing Times DVD's, CD's, and other products. It has been so beneficial to sign with my daughter. I recommend everyone start signing with their infant and continue into toddler hood and even beyond.
Here's the Baby Signing Times website for more information on their products: http://www.babysigningtime.com/
Also, I was renting the DVD's from the library for several months but finally decided to purchase them along with the CD's. I found an amazing deal (more than 50% off) at Baby Steals.com. Here is their website: http://babysteals.stealnetwork.com/
Just wait because the deal on their website will come up within a few months. I've seen it posted at least three times now, most recently a couple of days ago!
