An adorable COVID baby who previously had her older sister at home all the time has gone viral thanks to a series of videos showing how excited she now gets when her sibling returns home from school. Sammie Fay, 32, has shared dozens of videos of 18-month-old Olivia's daily boosts, when she sees her sister AJ's yellow school bus start to pull up. In a series of clips, an overcome Olivia bounces up and down with joy, waving her hands and stamping her feet before heading over to AJ, 8, for a long-awaited hug. The sisters’ close bond can be attributed to the fact that Olivia is a COVID baby, Sammie said, and so the siblings were initially “joined at the hip” as Sammie was working from home during the pandemic, meaning she was home for the bus with Olivia. Sammie started recording Olivia's daily exploits around September, once the toddler had gained enough confidence on her feet to run to AJ.
