AJ went through a phase like that. But it was just a phase--like most things with kids are--and eventually it passes, especially since they are usually eager to be self-sufficient and show how much they can do. I started 5 stepping A when she was 12 months, and I think the helping-with-everything phase came between 15-18 months and lasted less than a month. I saw it as a test--did I mean what I said when I told her I'd help? Would I really help or would I just try to cajole her to do it herself?
I know I go through phases of wanting someone to help me with everything--I just can't admit it because I'm an adult.
It'll pass, don't worry!
