But will it work?

The Sunday NYTimes, in an article by Amy Sutherland, “Modern Love: What Shamu Taught Me About a Happy Marriage,” taught me that marital frustrations can be trained away, much in the way that dolphins learn. Reading the piece reminds me of many parenting strategies I’ve accumulated over the years – don’t reward negative behaviors; focus on praising positive actions – but hey, it’s a new day, and I’m willing to try it on the older of my children :)  What do you think?  Can other people be trained, or are you simply training yourself?
