Answer: Pedestal sump pump
Explanation: Both submersible and pedestal sump pumps can be safe for homes with young children, but with some considerations:
Safety Feature: The biggest safety factor is having a secure lid on the sump pump pit. This prevents children from falling in, regardless of the pump type. Make sure the lid is bolted or screwed down and isn't easily removable by a child.
Accessibility: Pedestal sump pumps may be a slightly better option for homes with very young children. Since the motor is located above the pit, it's less accessible to curious hands than a submerged pump.
