Two is about the perfect age. At two your daughter is able to communicate with you and tell you when she needs to use the toilet. Girls usually learn faster than boys so she's probably ready right now.
Its not the age you are looking for so much as signs on if she is ready or not. Huggies has a free kit for potty training your little one, that has everything you need. Go to their website and order one!
Every child has their own time for doing things. It's a happy happy time when you find the diaper in the garbage, and you didn't even have to change it.
