Hi everyone, my 3 1/2 year has been good enough going to sleep. Obviously, had our struggles getting to bed but normally very good . We always bring her to bed and stay with hr till she sleeps. This last 4 weeks, her whole behaviour has changed, biting shouting hiting pulling hair at only me not her daddy especially at bedtime . It can take us up to 3 hrs to get her to sleep. We've tried usual routine books and quiet time . We shouted at her got really cross nothing works were exhausted wat else to do ? I have ordered a tonnie box as a last resort to see if that helps.
