Meal time help please.

Hi guys I need help with suggestions. My toddler is 15 months and throwing me tantrum when I feed her the meals, she is crying, yelling and still no food in the mouth. She used to be a perfect child before till now. I need to know some playful tricks or may be something to help both of us. And also I am trying my best to introduce more new foods but its a no no for her.
