What do you do about the power outlet and cables for appliances that are plugged in within your toddler's room, if they are no longer in the crib?

We have a heater/fan and the nightlight plugged in and the outlet is behind the bedside table but D'S could possibly reach behind and pull the plugs then touch the outlet.

We will be needing to transition him out of the crib within 5 months so wondering what people do about this or if its not an issue?
