Disclosure: I received the Little Tikes 4-in- 1 Trike free of charge to facilitate my review. All opinions are my own.
• Stage 1-Guided (9+ months) Parents to push and control-When the Red waist bar is installed the child will be unable to turn the wheel.
• Stage 2-Learning (12+ months) Toddlers can learn how to pedal, child is unable to turn the wheel
• Stage 3-Developing (18+ months) Remove the waist bar, child can now steer while parent still has control with the push bar
