June 18, 2017

UPDATED (Tuesday, 6/20):
We're now hearing more details about why the "Carter twins" remain hospitalized more than a week after their birth. 

TMZ says that the twins were born prematurely, and they are "under the lights to normalize. Of course, it is pretty common for twins to arrive a little early. "Under the lights" usually just means that the babies are jaundice. The condition is related to elevated bilirubin levels. So the lights are used to help counteract that.

It's not clear when the twins will be released. But this is a common condition, and we're hearing that everyone is expected to be OK.
