I believe the answer is: <span> Unlikely, because depth perception develops by about 6 months of age in infants </span><span>
By the time infants are crawling, they are able to perceive the environment around them and would tend to understand that the end of the bed is dangerous for them (since they could no longer see the environment beyond the end of the bed)</span>
The object must move with the speed of 
times to approximately seeing that it is contracted to exactly half of its actual length.
<h3>How is this calculated?</h3>
The length contraction experimented by the object as it approaches lightspeed, in meters per second, is described by Lorentz contraction formula:
Here, v is the current speed m/s
c is the speed of light in m/s
L' is the length of the object at rest in m
L is the length of the object at the current speed in m
Now we know that
and 
then,
Hence, r = 
Therefore, the answer is the object must travel at a speed of times the lightspeed to be contracted to one-half its proper length.

Epilepsy is a disease in the nervous system that is due to an unusual electrical activity in the cerebral cortex. Seizures and loss of consciousness are among the main characteristics of the disorder.
Generally, epilepsy is treated by means of anticonvulsant medications, however, sometimes the pathology is so severe that a surgical method is used.
