Shopping | (Thursday 4/11) Riley and Mariah arrive in Chicago a day early. With her daughter's 3rd birthday coming up in a few days, Riley invites Mariah to go shopping with her for her birthday present at the American Girl Doll store. Mariah excitedly accepts. Thinking it would be a quick trip to pick out Ella's present, Riley ends up spending hours in the store following after Mariah and reminding her that they're there shopping for a 3-year-old. Mariah ends up convincing Riley to have lunch in the American Girl Doll restaurant in the store.
