My guys go through phases too... so do I! Who wants the same foods over and over and over again? Different presentations, texture (raw/cooked), form (whole/chopped/shredded/etc) and such will offer enrichment and hopefully spark interest. And I can't stress enough how well "sharing" what you're eating works here at my house! They learn from their flock in the wild. You're her flock
Eat some peas yourself, make a big deal about it, be dramatic... show her how yummy they are! I usually opt for sugar snaps over snow peas b/c the pea itself is fatter... as long as we're looking at the same thing - snow peas are the flatter pods with little bitty peas inside. Anyway, you get the point. Sorry if I'm telling you things you already know
Keep trying. We're all wishing you the best! What a pretty girl she is!!
