I don't know if you've already done so but I would cross post this in the 4a section. Some of the ladies there may have some info. I would try to educate your sister on the harm that it could do to your neice's self esteem. No mom (speaking from experience ) wants their child to fell badly about themselves. I know there are books for your neice and sister but I personally haven't read them.
I also wanted to say that products that work on grown ups should work for her. There is still a level of experimenting to find out what her hair likes but my daughter is an itty bitty and shea butter and giovanni direct work for her too.
