There's a pattern for infant socks at www.sockknitters.com/patterns/infant. Maybe you can adjust your gauge and needles to make them for toddler size. They look really cute. My first afghan that I knitted was from a pattern that I got from Lionbrand, it was a ripple afghan made out of blue, cream and green. It turned out really nice and was amazingly easy to make, which for me at that time was important since I had just started knitting. Maybe the pattern is still there.

Here is another pattern at www.knitting-crochet.com/easbabsoc.html. I actually made these socks and the only thing I did differently was use a larger yarn. They definitely turned out to be toddler size and they were pretty easy to make too.
