I am at my wits end with my 3 yr old daughter. When she does something we put her in time out then "are you ready to say sorry to your sister for hitting her?" Answer "NO"..."well do you want to stay in time out or say sorry?" Answer "Stay in time out!"....and so on.
She has a very good diet (low in sugar etc) and sleeps well.
I have tried confiscating toys, time out, taking away pleasures - she just doesn't care.
I always take the girls swimming on a Wednesday afternoon and yesterday we did not go because she had behaved so badly I took away the "treat". That meant my 5 year old (who is fine) missed out.
She is a very loving and kind child and on the upside her tenacity is unparalleled!
Any ideas gratefully received please?
