"Mommy, can I have an extra scewp of ice cream?"
"Do you want a 'scewp' or a 'scoouahp'?"
"Which one is bigger?"
I hear my kid's accent (and mine as well, to a lesser extent) shifting to a central Midwestern one, and away from the Inland North one of southeaster Wisconsin. I don't like this, because the worser parts the accents in the area where we live now make one sound like a hick. (Not the above example, but other aspects, like that which drops the "to be" construction. Locals will say, "The carpet needs cleaned" instead of "The carpet needs to be cleaned.")
Yeah, that's right.
People judge you buy your vocabulary and spelling, and although regional accents in the US aren't generally terribly strong (with some notable exceptions), there are some types of sounds within the various regional accents that are stereotyped by most people, often subconciously.
So, while I never belabor the point with my kid or lose sleep of any of this, if she grows up sounding "General American" rather than Central Midland, that'd be really pretty great.
