Usually I say people should avoid violent reactions, but really your cousin is just plain dirty and wrong for this. I'm upset!! You left care instructions and all the materials, all she had to do was follow them, and she couldn't do that?? And what's worse, she decides to do the one thing you asked not to do! oh heck nah!!
Plus to me it seems she was waiting for a chance to make your beautiful little girls hair go down the drain...because why is her daughters hair still well managed??? hmmmmmmmmmmm??????
Anyways, I'm truly sorry this happened, but I say either put her in braids and actually even though she is eight, tell her what to spray in her hair at times (trust me you are never too young to learn to do your own hair--I started at 7 lol). And possibly find someone..a church member, a mother from her school (idk), I don't know, someone willing to help..it's just sad her own grandma and aunt's couldn't even care less.. sigh..
your baby's hair was so pretty before you left! ugh. i hate when folks use relaxers on a baby's hair thinking its some kind of solution, and it ends up bein the problem. it ate her hair up!
your cousin, then get your daughter some braids. She should not have to do battle at home, when you just left it. And thank you for that. I know you will make it OK. After you get through 
your cousin!
. Im so sorry to hear and see what yoru cousin did. 
I can't believe you cousin had the nerve to perm her hair while you we gone. I am so sorry. My only suggestion would be to trim hair as close to one length as possible and do a protective style for a little while.
erplexed. I hope she offered an apology...
