Why does a child feel more pain when she falls down on a hard cement floor, than when she falls on the soft muddy ground in the garden?

Tough cement floor is robust and tough whereas a muddy ground is soft and cushiony. When a child falls on a cement floor, the force acts on the child instantly and thus the impact is more. To reduce the impact of force, we increase the time of action of the force or we could increase the distance travelled by the object. This is what happens in a muddy ground. As the momentum is gradually changed over a due course of time in a muddy ground, the impact is less and the child suffers less pain.
