Other than curse words of course. DH was telling me a story and mentioned the phrase "oh it's so stupid". DD kept repeating the word stupid over and over again! Eek! I know it's not a bad word but I didn't want a two year old to start saying it. Would you try not say "stupid" in front of your LO or do you think it's no big deal? Any other words you try not to say in front of LO?
