Dennis Quaid's newborn twins are in "a stable condition"

Dennis Quaid's newborn twins are in "a stable condition" after being given an accidental drug overdose.

Thomas Boone and Zoe Grace - who were born via a surrogate on November 8 to Dennis and his wife Kimberly Buffington at Los Angeles' Cedars-Sinai Medical Center - were left fighting for their lives after mistakenly being given 10,000 units of the anti-coagulant Heparin - which stops the blood from clotting.
Babies are only allowed to have 10 units.
Although the twins are in a stable condition, an authoritative source at the hospital said: "Doctors are still very concerned because of the bleed out. It will not be determined for another week whether there will be long-term effects."
