It’s the family dynamic parents dream of: a protective older brother watches out for his baby sister. And for newborn Ruby Jane, that protectiveness is sixfold. Corey Lowenstein of The News & Observer shared a video (watch it here) of six big brothers meeting the newest addition to their family: a baby girl. As they candidly share their reactions to having a sister, we feel confident Ruby is in excellent hands. Here, each of the boys’ best reactions. “Mouth? Head?” -Knox, 2, using his new baby sister to practice anatomical identification. “She is cuter than I thought she would be.” -Shepherd, 4, reluctantly fessing up to liking Ruby. “When she’s five or six or seven, she might get paint and just paint pink everywhere.” -Houston, 5, projecting worst-case scenarios. “She’s as precious as a ruby. And if I lost her, I would join a police force, and I would definitely get whoever did it.” -Sawyer, 7, making us laugh and cry at the same time. “When she gets old enough and she has a boyfriend and she brings him home, all she’s gonna say is ‘Meet my bothers. To have me, you’re gonna have to go through them.’” -Campbell, 10, confirming what we were all thinking. “She’s so small! I didn’t even think babies could be this little.” -Jackson, 13, still awestruck after six siblings.
