All kids mispronounce things. It's a part of speech development, and pretty cute. Sometimes I think the way my girls have mispronounced certain words, are actually an improvement on them. We've come to use the improved version in our everyday speech at home. If you ever hear us use the improvements instead of the official word, I have provided the Andrews Sisters-English translation below, for your own personal reference.
For your convenience, I've listed the words in alphabetical order.
Dusting Panner (Dust pan)
Hinny Minny's (Frosted Mini Wheats)
It's a short but cute list. After all, we do have smart little girls who love to talk, so mispronunciations aren't in a great abundance. I'm not actually convinced that's what these are, to be honest. They're more like creative interpretations of the words. Feel free to add them to your own vocabulary!
Now if you'll please excuse me, I need to go use the dusting panner to finish sweeping up the breakfast mess my girls made from marshlellow and Hinny Minny cereals. I'd ask Anny to help me, but she's busy using her binanan lellow hoopa-loop.
