Dylan refuses just about everything except his dairy free margarine and grape jelly
What I do is offer one half of his bagel or toast with just his margarine on it, and the other half with some sort of spread (a different jam or jelly, or fruit puree, thinking of trying honey soon since he is almost 13mo). That way I am offering it, assuming that some day he'll decide it's interesting enough to try, but I also ensure that there is something on his tray that he will eat. I have heard that los sometimes need to be exposed to something dozens of times before they will try it, and the trick is to just keep offering
HTH
