picky eater Toddler

Hi mommies, I have 2 year old toddler, until now exclusive breAstfeed parin sya, so para masustain yung body nya, i prepared nutritious foods pero ayaw nya, before kumakain sya ng vegetables, pero now fish and minsan chicken lang. Ayaw nya din ng lasa ng formula milk, para sana kahit papano may supplement sya. Ano pwede gawin sa picky eater toddler? Thank you
