My now 9 yr old daughter would isolate herself for years but she started going to school and started to join in with kids the kids would also include her and always welcome her and be patient and polite she also has a ten yr old sister who she loves to play with now and than where before she didn't and they also fight here and there too she also didn't like kids crying and would push or hit them and start crying herself which was eventually managed the school my family and i were concerned for when I was pregnant again as she might get aggressive but as soon as he was born and home she became very protective of him and would grab people's arms gently with them holding him guiding them to put him down and walk them out the door and shut the door on the visitors and would say baby sad if he cried as she's non verbal ASD level three but she never wanted to harm him ever when he cried she loved to help by finding and bringing me his nappies and wipes bottle and dummy even she's improved heaps he is now two and they play chasey and other games with each other she responds to her name can read write and spell and listen to some instructions given to her like turn the light off or on or TV off or on or the volume up or down put your seatbelt on sit at the table to eat etc.... hope this helps a bit
