Chances are, you are too. Because, toddlers are masters of selective hearing...
I present an excerpt from; I'm a Lazy Doormat.
There is a growing problem going on in my house right now; Confusion over the meaning of the word no, and the number of times I use it in a row. Basically, the issue is, I say “No!” to Oliver, and most times, he just kind of stares at me, clearly trying to decide what I am going to do if he doesn't listen.
Then nine times out of ten, I say “No!” ten more times before anything happens. I know what you are thinking, if “No!” means, “Stop that right now!” then why do I say it 10 times in a row? I will tell you why, because of these two reasons:
HAHAHAHAHA!! Let me tell you how well that plan worked...
Two years later, I'm still saying, No!, a few times in a row before getting off my lazy butt. The Toddler's selective hearing is no better, however, his understanding that I'll get up off my ass sooner than later does work well as a deterrent.
The bottom line is that toddlers are special little people. They have no desire to give up control, at least not without a fight. The trick, is not giving in, staying consistent, and what ever you do, say No, ONCE, then take action. Or, face my fate, and have a toddler that thinks he has at least 10-30 seconds before shit gets real.
