Baby Penelope (immediately above) arrived as a present for Mabel Watson Payne's first birthday, more than a year ago. When I came over to babysit on Monday afternoon I found Penelope dressed in one of Mabel's own pull-up diapers. It had been induced to fit the little rubber doll better than I would have expected, another manifestation of the potty-topic that Mabel continues to investigate in her own way at her own pace.
