Outnumbered is a British sitcom about a most ordinary subject, in a way: family life with three children. As you guessed, Ramona is one of the children, Karen, and in my opinion superb in all ways, including the perhaps fundamental requirement of being funny in a serious, naive kind of way, as is fitting for a small child. The style of the show is very realistic, so there is little in way of cutesy silly things that children would say, or actual jokes being told. For my sense of humor, scenes like where Karen brings home a drawing she made in school about a cow killing people since he doesn't want to be made burgers of work perfectly. And all that in a very British accent.
