Mouth of Babes

When you have a newborn, your language filter has not quite kicked on yet. You are able to speak freely, watch R rated movies, and drop an occasional curse without fear of influencing this very impressionable being.
As the child grows you become so used to having him or her around that you sometimes forget that they are beginning to comprehend more and are developing their own language.
Neither Matt nor I have "foul mouths" but on occasion we, like everyone else, use expletives that may not always be appropriate, especially to a toddler that listens and absorbs everything.
It's not just the listening that one needs to be aware of it's the repeating of such phrases and/or language that we fear.
Chloe was playing with her match cards the other morning while Matt & I were drinking a cup of coffee and having our own conversation. She dropped her cards and very matter of factly cries out: "Oh S**T, I made a mess!"

...mommy will take the blame for that one :)
