At 15 months, my son repeats the "S" word yesterday. There's no doubt where he heard it, as I had just shouted it out 30 seconds before he said it.
Now, anyone who knows me very well is aware that I've been known to curse like a sailor- maybe even worse. But since the birth of my son I've done very well to think half a second longer before I "shout out." But apparently I haven't done well enough- or I thought I had more time before I had to work harder at it :)
So where I am now- beating it into my brain that I have a toddler and MUST do more than Practice self-control over my mouth!
