WASHINGTON (WUSA9) -- A sloth bear cub born at the Smithsonian's National Zoo on Dec. 29 has been named Remi by the her keepers, zoo officials announced Thursday.

Officials said her keepers have been hand-rearing the cub 24 hours a day since a week after she was born, becoming her surrogate parents.

The keepers have made sure Remi sleeps soundly through the night. Remi used to sleep with her eyes slightly open when she was very young, zoo officials said.

Her keepers decided to name her Remi from the REM (rapid eye movement) sleep cycle. The baby sloth bear will be on exhibit this summer at the sloth bear habitat on Asia Trail.
