Naomi Watts and Liev Schreiber's toddler son has been released from hospital after an overnight stay earlier this week.

On Tuesday 21-month-old Alexander 'Sacha', older brother to four-month-old Samuel Kai, was admitted to hospital where he was treated for breathing problems. 
 
The youngster's dad Liev, who stars as Sabretooth in new film X-Men Origins: Wolverine, was absent from the movie's LA premiere on Tuesday having flown home to be with his family.
 
After an overnight stay, Sacha was able to return home.
 
"Sasha got home today and is feeling much better after being hospitalised on Tuesday night with respiratory problems," the 41-year-old actor's spokesman confirmed
