hi im new

hi

I have a partner who has a son with autism from his previous marriage, his son is 10 and he comes to stay with us every other weekend and spends sometime with us in the hoildays. i have a 5 yr old daughter and i have found it difficult to try and explain autism to her. she is enjoys spending time with him and listening to him talk about things. he also has a sister who gets on very well with my daughter and i think because he doesnt get on with his sister very well he has become jealous and has started taking it out on my daughter saying nasty things to her and about her, she doesnt understand and gets upset at times. I dont really know how to get him to stop doing this or where to go to for advice. i would be very grateful for any help you can offer.
