Thank God its not just her..
I seriously think I will lock myself in my room for the next 5 to 10 years between her and Rachel..I hope you all are right and it does get better..
as far as letting her help me cook I would love that but she whines and throws a big ol fit when its time to clean up the cooking mess. So I tell her if she cant help with the not so fun stuff then she cant help with the fun stuff.
