Little Max, one of the twin sons born to Sheen and his wife, Brooke Mueller, has remained in the hospital since his birth on March 14, reports People.
"Charlie and Brooke’s infant son Max remains in the hospital, not because of a heart condition as reported, but because he has not gained the weight necessary to leave the hospital," said the actor’s rep, Stan Rosenfield.
Max must reach a certain weight before he is given the green light to go home to be with his brother and parents.
"The weight issue is very common among infants who were born before reaching full term," explained Sheen.
Max and Bob are the first children for Sheen and Mueller. The actor also has two daughters with Denise Richards, Sam, 4, and Lola, 3. Sheen also has a 24-year-old daughter from a previous relationship.
