My friend is having a stressful time recently so i have been having her dd 3 mornings a week to give her a break. She is a lovely girl, but she keeps pushing other toddlers. There is no trigger for this - they have not necessarily done anything to upset her, she just gets a cross look on her face then pushes them. I think it may be attention seeking as she usually looks at me when she is doing it. I cannot ignore this. I bend down and say calmly to stop, we don't push then make her say sorry which she does. However, this behaviour occurs again and again. Any advice would be hugely appreciated.
