Sammy's favorite word of lately is "NO", which I'm sure surprises everyone (almost 2). So when he says no, I tell him to use nice words, like "okay", "yes", etc. So here was the conversation today after church when Sammy was playing with Isabel's princess wand. This was all Isabel and Sammy. I just watched.
"Sammy, I want that"
"Sammy, use nice words, like yes"
"say yes Sammy"
and that was pretty much the end of that conversation. She ended up with out the wand and Sammy keeps yelling NO at everyone unless you offer him some candy or a popsicle. I thought Isabel's skills in trying to effectively get what she wanted were very clever!
