Many of the toilet seat based bidets (such as the Brondell Swash) have sensors in the seat that won't allow the water sprayer or blow dryer to run unless contact is detected from someone actually sitting down. That's what relieved my concern about it. I have a toddler who likes to press buttons, too! He just presses them and nothing happens. You can also just turn it off and completely deactivate it by holding the stop button for 5 seconds.
