Today I met with my sister,excited i was ,for i haven't seen them in quite some time. But to my dismay my niece is now 13 and has a speech disorder and has the demeaner of a four year old. My sister is home schooling but this my be a bit much for her.She appears to be depressed and very sore on the subject of her daughter,but I pressed the issue and she believes her daughter is fine,even though they are like hermits. She refuses to seek outside help an advice.My concern is for the child and her future.How do help her and my sister
