Rocky James Prinze was born on Sept. 19, 2012, only six days after his big sister's third birthday. "Mother and baby are doing great. And Charlotte is VERY excited to be a big sister," a representative for the family told Us Weekly following Rocky's birth. As with Charlotte, Rocky has mostly been kept out of the spotlight by his parents.
Sarah did talk about Rocky in October 2020, when she spoke to Today's about discovering that he has myopia. Initially, she explained, she chalked it up to eye strain from switching to full-time online learning amid the pandemic, but she soon realized there was more to it. "They said not only did he have myopia — the common term is nearsightedness — but it was progressing extremely rapidly. . . . You have to go with your gut as a parent," Sarah said. "I think that's the best advice I've ever learned. You know your kid." Rocky apparently is not interested in wearing glasses, partly out of concern that it would affect his ability to play sports, but has been adapting to contact lenses.
As a family, they stay active together. "We're pretty strict about screen time," Sarah added. "During the school day screens are only for school, so there's no television, there's no texting friends, there's no nothing. As soon as school's out, we try to do physical activity outside as a family whether it's hiking or taking a walk or biking or swimming. We've also gotten really into board games."
