Which reflex must disappear before a child can take their first steps?

The plantar grasp reflex, which involves the curling of the toes when the sole of the foot is stimulated, typically starts to diminish around 9 to 12 months of age. This is significant as a child matures and prepares for walking. The presence of the plantar grasp reflex can interfere with the child’s ability to stand and take steps, as it suggests a primitive reflex that is not aligned with the more complex motor coordination required for walking.

As the child develops and achieves other milestones, such as improved balance and control over their movements, the disappearance of this reflex indicates that they are ready to engage in more purposeful locomotion. Once this reflex fades, it allows for the normal patterns of weight-bearing and stepping to emerge. Thus, for a child to take their first steps, the plantar grasp reflex must be absent, enabling smoother, more coordinated movements essential for walking.
