Sarah chooses which narrative she wants for each particular day. One day her followers are her "best friends, know everything that goes on in her life, she's open about everything, real, raw, honest" and the next day, she's like "I don't share everything, you don't know what really goes on in my life".
It's Instagram, she knows people pick up on small details, why did she show the two prams anyway? Funnily enough, she showed 5 or 6 messages asking if she's pregnant, yet for every sponsored product, she gets "hundreds of DMs".
