Biden responded directly to Layla [who is 9 years old, as given in the article], explaining that kids were not at a high of a risk of getting severe COVID-19 infection and that the vaccine for children wasn't ready just yet.
"Don't be scared, honey. Don't be scared. You're going to be fine, and we're going to make sure mommy's fine, too," Biden said.
The dictionary definition of 'honey' in this context is: (informal) darling; sweetheart (usually as a form of address). This sounds like an awfully intimate way to address an unrelated child. But Biden was speaking on the record, which means he must be choosing his words carefully, so I'd like to confirm.
