Have I tried any of the languages on my own kids? Do I do any of the things I suggest? Have I noticed anything?
Yes, I have used these products myself--I mean, yes, I have applied these things to my own life and kids. On days when I ask my kids to do their chores first and play later, I get the usual whining, complaining, arguing ... But when I take the time (usually on a Saturday morning) to play a video with my older daughter right after breakfast, I find she is more willing to be helpful. Does it work perfectly every time? No. I am not perfect, so why should I expect my kids to be perfect? I have noticed an improvement, and that's what's important to me :)
