I, too, read this entire thread hoping for the happy ending with the child and parents reunited. Since there was never anything in the news or on the Amber Alert, I'm hoping that no news is good news. I have a hard time believing that a child disappearing entirely from WDW wouldn't make national news.
I'm also disappointed that this thread seems to have dissolved into an argument or at least what could mildly be called a disagreement. I doubt that there is a parent anywhere that doesn't think they are doing what is best for their children. (Although, I'm not exactly sure how teaching your child to call another child a name ie 'cute puppy' fits in here.

) Having said that, I will confess that before I had kids, I was the world's best parent. I made judgements about every other parents' way of doing things without having a clue. MY kids would never go in public with a dirty face, MY kids would always hold my hand when we walk somewhere, MY kids would follow all the rules. All I had to do was explain the rules to them first. My theory flew out the window the day I heard myself say to my SD, "Honey, please stop licking the bottom of your shoe." I realized that there are literally millions of different scenarios that could happen and that the best you can do is the best you can do. I try to plan for the worst, but expect the best.
I will keep my eyes on my kids as much as humanly possible. I can't say 100% of the time, because I know that there will be the inevitable bottle that slips to the bottom of the diaper bag I might have to search for just for a couple seconds.
I will hold their hands as much as humanly possible. Again, 100% of the time is out because there is usually at least one shoe that needs retied or a nose that needs wiped.
I won't use a harness, but that is my choice. I confess that I will probably be assuming that a harness is for safety and convenience rather than a develpmental tool. I also confess that I have used a stroller as a restraint device when I shop at the mall, so don't think I'm claiming I'm better than anyone else. Just different.
I will NEVER teach my child to degrade another child for any reason. In fact, I can state unequivocally that I will teach my child the opposite and hope they learn compassion. I would always hope that my child would first think of how they would feel if someone said that to them.
I will plan to watch my child completely while at WDW, but I will also plan to have a backup plan. I believe the saying goes something like, Those who fail to plan, plan to fail. And to fail in the planning of my kids safety is just beyond my reckoning. It takes such little effort to plan for a backup that it almost seems negligent not to do it.
As for parents being responsible for their child getting lost, I think that I have to agree. Ultimately, we are responsible for our children's safety. Just as I would be responsible if my son fell and hurt his knee playing tag in the park. I could have wrapped him in cottonwool and never let him outside to play, but I didn't. I will take precautions and do the best I can. I will take responsibility when things happen, but the truth is....things happen. I just hope and pray that the worst never does happen...and if it does, let me have a back up plan in place (Please, God!!). In the case of the scraped knee, a bandaid in the purse was all it took, but I also know where the closest Ugent Care is and carry the cell phone pre-programmed with 911.
I think that the idea about putting ID with cell phone number hidden on the child, whether on dog-tag, shoe lace or other, is a great idea. A child that is frantic and crying may not be able to speak clearly.
I LOVE the idea of taking a digital photo of the child each day in the clothes they are wearing. Whoever came up with this one should get some kind of Nobel Child Safety Ingenious Idea Award.
I'm not sure about the two-way radio thing, though. I've read that since they have become common in the parks, they are often hard to use since so many people are on the same 'channel'. I think cell phones would be a better bet if your kids are old enough to use electronic stuff.
When you are telling your children to go to a CM if they get separated, how do you tell them to recognize them? It has been a couple years since we have been there, but WDW had Guest of Honor Badges that looked very similar to the CM badges when we were there last. Are they different now?
I have faith that Disney has great protocols for lost children, but it is easy for me to say since my kid isn't lost. At first I thought the comment about refusing to stop or postpone the fireworks was based on economic reasons, but someone else said that it would be easier to search if most people were standing still engrossed in the show. It made total sense once it was pointed out. I guess that what I'm saying is, just because we can't see what might be obvious to security and the CMs, it doesn't mean that the best isn't being done.
I hope that, if anyone out there reading this feels judgemental towards a parent that has lost their child, you get to spend the rest of your life never having to say, "After having a lost child, I know I was wrong."
