We went through a similar phase with my son (now 22). It's probably puberty kicking in, which is tough on all kids and even harder on our ASD kids. Does she have anxiety about baths or going places (which might explain the avoidance)? Is there something you could use as a reward for bathing/going places? The good news is that eventually all phases pass with time. Just don't blame yourself or feel like you're doing something wrong--you are doing the best you can. :)

She does have anxiety about those things. She will run away or at times get aggressive. Thanks for the info and reassurance that things will get better.
