It could be any/all of those things
Is this her first big distractibility phase? There is SO much going on at 12mo. Learning about food and choices is one of the big ones. Saying "no" is so much fun b/c it shows control and choice (even if she really wants to say "yes" :LOL ).
Babies slow down their physical growth a lot too. My oldest 3 all stopped growing around 9mo and just sort of plateau'd for a long while and didn't eat so much (bm or food) b/c they were busy. They had better things to do.
I'd say as long as she has a couple sessions at the breast with true gusto (and I really mean that last a long while and get into the hind milk, etc) like at night or in the morning then she's probably not weaning. My children definitely didn't wean just by cutting down on their day nursings at this age.
