I'm a 9 year old and I think she doesn't like me I'm nice to her and want to spend time with her but she doesn't understand an as a 9 year old it's Horrible if any one understands me . I have a sister that's 20 and treated her well till my sister did't like her also then I came along so like for the past years she's been super nice but now she say s I act like a 2 year old now but I don't act like that . So if any body I mean anyone can help me that would be awesome ! Thanks

Does she say how you act like a two-year-old?

Talk to your mom about your feelings.Talk to your sister. Talk to your school counselor. Talk to a teacher. Talking about your feeling makes you feel better, and gets adults who care about you involved in your life. You stated your mom has been super nice to you for the past years, so she does love you. Talk to her about her change in behavior towards you. She may not realize she has treated you differently, and the change in how she is treating you may not have anything to do with you.
