Dd1 (nearly 8) can do many of these and the rest when reminded or slightly assisted. I was doing all of those things by myself at 11.

Could she do them previously and has since stopped or has she been resisting doing them completely?

I think it would be a good idea to look into the reasons why though. It may just be her personality or level of developmental maturity or that she is the youngest and wants to stay that way. However there could be other things at play and you may need to use different strategies with her. What does your gut say?
