Naomi Watts is helping her baby boy recover after he was rushed to hospital on Tuesday.
21-month-old Sasha was taken to a New York medical centre suffering respiratory problems.
He has now been discharged following an overnight stay.
Naomi's partner, Liev Schreiber, missed the Los Angeles premiere of his latest flick, X-Men Origins: Wolverine, to be by his family's side during the traumatic time. 
A rep for the actor said Sasha's condition is now very much improved.
"Sasha got home today and is feeling much better after being hospitalised on Tuesday night with respiratory problems," Ina Treciokas told People.
Naomi and Liev got together in Spring 2005.
They have two children together; Sasha and Samuel, born last December.
