A folding control mechanism for a collapsible baby stroller has a pair of push arms each comprises an upper segment and a lower segment. The upper segment and lower segment both are lockable connected by a pair of first articulated joint. An actuator is mounted for unlock the first articulated joint by pulling a pair of first connecting member, to allow the upper segment capable of pivoting about the first articulated joint to close to the lower segment. A driven ring is installed in the first articulated joint for unlocking the second articulated joints by pulling a pair of a second connecting member while the upper segment of the push arms is rotated about the first articulated joint in a predetermined angle. When the second articulated joint is unlocked, the stroller frame is transferred into a collapsible state.
