My DD1 will be 11 next April. She can do all the things on the list except she does need a hand with her hair as it is very fine, very thick and down to her butt! She can tie it up before a shower if she's not washing it, but I usually do her hair on on school mornings and usually check that she has washed all the conditioner out before she gets out of the shower when she does wash it.

DD1 can also cook a meal on her own (with assistance to take heavy dishes out of the oven), bake a cake, mix up horse feeds, bath the dogs...

As others have mentioned, I think you need to figure out whether your DD can't do the things on the list or whether she won't do the things on the list. I think I read that she is your youngest and I wonder if that is a factor? Still expecting to be babied? My DD1 is my eldest child and sometimes I think we expect a lot of her! Maybe give it a week of encouraging to do those things for herself and if it appears that she is simply not capable, maybe it's time to have a chat with a paediatrician.
