Over the years, the editors at American Girl have received countless letters from girls who have written to share their experience or ask for advice about adjusting to a new stepparent or stepfamily. While every family is different, and changing family dynamics will affect each girl in her own way, common themes—like feeling nervous about change, pressure about accepting a new parent or sibling, frustration about conflicts, and uncertainty about rules—run through so many girls’ letters that talking through these issues may just offer a good place to start if you see your girl working to find her balance as you grow as a family.
