According to an update on Spears' Web site, 2-year-old Jayden James has left the Southwest Mississippi Regional Medical Center and is doing fine.
A representative for the Spears' family says Jayden was admitted Sunday after having "a reaction to something he ingested."
The hospital is near Spears' home in Kentwood, Louisiana, where the singer was reportedly staying with family. Representatives for Spears and her family didn't immediately return messages left Tuesday.
Spears and ex-husband Kevin Federline are also parents to 3-year-old Sean Preston.
