This little girl showed an instant sibling bond with her newborn sister - creating an adorable lullaby to help her to sleep the first time they met. Sweet Jayda Brennan had just become a big sister for the first time and, when being introduced to her sister, started singing to baby Rayna to help keep her calm. The immediate, heartwarming connection was caught on camera by their mom Shannon Brennan, from Rochester, New York, at Unity Hospital. Shannon, who shared the video online on March 29 2018, revealed Jayda had been asking for a little brother or sister for quite some time and was ecstatic her wish came true.
