I think that for me, if I don't take some chances and allow some indepenence then I am failing my kid. The world is full of risk and we simply cannot shield them from all of it all the time and expect them to become functioning adults. In reality,this is EXTREMELY low on the risk spectrum but in our minds as parents it has taken on epic proportion. The number of kids harmed by and adult becuase they went to the bathroom alone is orders of magnitude less than those harmed becuase they played sports, went to school, were scouts, or any number of other things, but we don't think twice about allowing those things. I have to wonder why that is? Why is the bathroom so taboo, but other higher risk locations ok? What is it about our society that attaches molestors to public restrooms? I have always found it interesting that THIS is the hot button topic, nad molestors are always brought up, but no one thinks twice about thier sports coach, sout leader, realtives, ect being alone with their child. THESE are statistically much more likely to be where the threat comes form than someone lurking in a restroom, but we focus all our energy on the unknown stranger, and not on those our kids know and trust.
I am a little exhausted on this topic but here goes....
Why does one always bring up the unknown stranger vs the person we know and trust as if you are cautious about the one you will not be cautious about the other?????
I take precautions everywhere with my kids. Accidents happen but I make sure my car is in good shape, have them wear seatbelts, car seats (when they were little) etc, all to minimize the risk!
I have them wear helmets when biking bc even though I never wore one as a kid and never got a head injury, it has now been deemed safer for them to ride with a helmet, all to minimize risk, but actually how many head injuries really occurred probably quite a low number since we all survived childhood.
Now onto the coaches etc, I only sign my kids up for activities that have strict background checks. Up to a certain age, I dont leave them alone at practices or games. I talked to them about inappropriate touch. And when I, me the parent deems it appopriate, not some magical age that society says, it is based off of maturity and situational, I will allow them to stay at practice without me. But I talk to them about being safe.
I do/did (my boys are old enough now), I talked to my boys about the stranger in the bathroom as well as the one driving along the road asking for a lost puppy. I have talked about men who like to expose themselves to young boys etc. But until I, me the parent feels that my child is capable of handling these situations, I will do what I need to do to minimize the risk. If that means taking him into a restroom so be it.
None of these are mutually exclusive...I hate when the assumption is that bc some parents fear the bathroom too much they dont think about the people close to them.
Also to the poster that says nothing has ever happened in a WDW restroom, I certainly dont want my child to be the first. And with the reports of security guards dealing in child porn, I dont think WDW is the safe bubble some people think it is.
If DH isn't with me, I stand outside the door and wait. He's gone into bathrooms before where the paper was too high for him to reach...I'd hear him asking some man in the bathroom to get him some paper. Apparently, he's OK.
