You know what I mean, "ouch-y" or "pac-i". Or blank-ie. Where did this come from? It's not like my kid is not going to like something just because the word I'm using ends in a hard sounding consonant. Honey do you want your blankie? Yes please. Honey do you want your blankET? AHHH noooooo! Not the blankET!!!!!!!!!!!!!!!
Does an IE or Y at the end of the word make the item all that more appealing? Na. So why do we do it? I'll admit I'm the first one to throw around an Icky or shoeys. And heck I think I've even said "did you get a booboo-ie?" Booboo-ie, what the hell is that?
There are many appropriate times to add the Y. Like mommy and daddy. Or poopy. Those are three staples that must not change and sound perfectly fine.
But for the other instances do we realize how stupid we sound talking to our kids? Do we care?
