Well yes, because he's a cheating cheater who cheats
I thought this was a universally accepted truth.
Ah yes. It's easy to be a perfect parent when you don't have kids. I too, was an amazing parent before I actually was one. Then I had kids, and I'm probably a fairly good parent, but I'm going to guess that if some of these people saw my parenting in action I'd be lumped in with "those parents who don't watch their children".
Been there, done that. Not at Disney, but plenty of other places. There have been a few times where I carried my oldest out of a restaraunt because he was throwing a fit. But lots of times where he has been throwing a fit, on the floor crying, in public and I let him. And guess what? He learned that throwing a fit does not get him his way, or the attention that he is looking for. I'm sure there were a few judgy judy's starting at me thinking "I can't believe she's just ignoring him! What a horrible mom. My kids would never!" But most parents were giving me the "that sucks and I'm glad it's not mine, and do what you gotta do" vibes. I'd much rather deal with that a few times and have the lesson learned than to placate my child everytime something doesn't go their way and encouraging bad behavior.
