It is a worry the first few times they do it - I jumped to grab DS quite a few times when we first started on solids too. But I agree, if it's doing your head in then maybe ease off. They do get better though, and quickly. i would say too the more practice they have the quicker they'd get better at it, most probably.
But wow on her using a spoon pixie! I'm impressed. DS still can't do that...
