Help!!! I have found a lovely Au Pair (as I am going back to Uni and can't afford a childminder) and all seemed to be going well for the first week but now my ds1 (4) has really started pushing his luck with her and being a total brat. He is very strong willed at the best of times but is usually very loving and responds to a severe *ing and 5 mins in the "sin bin" I have told the AP to use the same techniques but she seems reluctant to lay down the law with him.
Ds1 has just started at school so I expect him to be a bit unsettled but it is not as if I have abandoned him as I don't start Uni until Jan.
To make matters worse DS2 (3) is acting like an angel so ds1 looks even worse by comparison!
Any ideas? Should I intervene and discipline him when he is rude to the AP or leave her to deal with it?
Sorry its such a long one!
