Trying: parents' guide

Very little. Comic moments include Nikki snatching a stranger's phone and hurling it into a pond. Arguments and minor mishaps, but no one is seriously hurt in the episodes reviewed.

Regular s-words, about seven in the first episode by one count, plus British insults like "prick," "wanker" and "bloody," and frequent "oh God." Reviewers did not report f-words.

Sex is a constant topic since the couple is trying to conceive. The opening scene shows them having sex on a night bus with their clothes on, and another cuts away as they tumble into bed. A friend's affair ends his marriage. No nudity.

Adults drink often at pubs, dinners and gatherings, including a man who downs three glasses of wine and then can't drive. No drug use or smoking is reported.

Nothing scary. The strain is emotional: infertility, setbacks in the adoption process, the children's painful history and questions about their birth mother, and the deaths of Jason's grandmother and, in a later season, the children's grandmother.
