Before the four letter words fly, remember most young children have no idea what those choice words mean.
Experts say if you ignore the word, it may not be used again. Normally what makes children use those words is the response or reaction they're getting from those around them, especially at the age they are testing the limits.
Kids pick up swear words quickly, so they are learning them from parents, television or people around them. So watch what you say and remind those around you to watch themselves.
Chances are one will slip out of your child's mouth at some point. Experts say how you handle those potty words can either help tone down the language or backfire on you.
When it happens the first time, ignore it. Your kid will be less likely to say it again if he sees you don't find it amusing.
The next time, stay calm and say, "That's not a nice word, and we don't use it in our house."
If foul language continues to be a problem, make sure you -- and the other adults around your child -- are being good role models. Also monitor what's being shown on television.
If you slip up with a curse word, don't sweat it. But acknowledge your slip by saying I should not have used that word and then carry on as if nothing happened.
