Beginning Potty Training?

We went out to dinner at the Olive Garden this evening to escape the heat (it was 105 outside, 85 inside). As we were waiting for our check, Abby casually looked at me and said, "I have to go potty, Mommy." I was a little surprised since we haven't really begun potty training yet, but I jumped on the opportunity and took her to the bathroom. Sure enough, she went! So I guess I'll get the potty chair down from the attic and see if she's really ready to do this. It would be wonderful to have her out of diapers soon! I know it may be a fluke, but I was so proud of her tonight!
