Strangely enough, we have hit a blueberry go-slow as well. Small has not yet rejected them completely but they are the last things to be attacked and she has pushed the bowl away before finishing them. The new-favouritist-thing-instead is grapes - can't get enough of them and its very annoying as grapes require Mum-intervention to prepare them. Grrr..... I think Small has phases of things and the blueberry phase has just lasted longer then most. Given how often I have served them up she has probably just eventually got a bit bored!
