The young actors who played Sheldon and Georgie have come back together after the series finale of Young Sheldon. Iain Armitage stopped by to meet his co-star, Montana Jordan's, newborn daughter. He shared a video of himself on Instagram singing the "Soft Kitty" song to the baby, a reference to its appearance in The Big Bang Theory. Armitage also shared a heartfelt paragraph about meeting his "niece" for the first time. There is talk of involving the older Georgie actor, Jerry O'Connell, in a spinoff called Georgie & Mandy's First Marriage.
