I've got two adorable things my girls used to say...
My oldest daughter, Deborah (now ten years old and entering 5th grade) used to say she was going to "cl-olor a picture" instead of "color a picture". She said that up until she was in kindergarten. I miss that one.
My youngest daughter, Abigail (almost eight and going into 3rd grade) used to say she was going to take a shower and wash her chest and her "nibbles", rather than her "nipples". Harder to catch this one and help her fix it since most people don't go around talking about their nipples. She really didn't get the difference until she was in first grade. She still sometimes substitutes and "F" for a "Th", but she knows the what they sound like now, she just kind of lets it slide every once in a while.
It's true that I want my girls to grow up, change and experience life, but there is a part of me that misses their baby hugs, smiles and words. I don't want them to be trapped in eternal child-hood, but much of that time was precious, simply because it is forever gone. Except for in my memories.
