Calvin's first outing in underwear

I know...I felt very brave doing this. Considering we've only been seriously potty training him for about a week. He's gone on short car rides to pick up Violet from preschool before wearing undies but I don't count a 10 minute trip out of the house to be worth much. Anyway...some friends of ours invited us over for dinner tonight and we were out of the house for three hours - and he used the bathroom four times with no accidents - I am soooo proud of him!
