My DS1 who is 3.5yrs has just started to swear. Yesterday he was telling DS2 (2yrs) off and then said 'fucking hell' - I was horrified and ignored it. Then today he started saying it again, at first DH and ignored but it got to the point where we had to explain that they are not nice words and he shouldn't use them and if he did we would give his new bike away to another little boy. Obviously he doesn't value the new bike yet as he continues to say it and sometimes with a grin which tells me that he is saying it to get the attention.
Can anyone recommend a tried and tested way how to handle this?
