My 4-year-old DS1 and 23-month-old DS2 have just discovered swear words. DH and I swear occasionally, but we aren't chronic swearers or anything. Regardless, it is our fault and they have picked it up from us. I now have an issue where my 23-month-old is dropping the eff bomb regularly, and in public too. It is dreadful. Any tips on how I can get my boys to break this habit? My 4-year-old isn't as bad as the 23-month-old.
