SAME FOOD

My toddler who is three years old wants to eat nothing but cereal or Dino bites I cannot get her to eat anything else she refuses , cries And would rather drink her water then eat anything new or things that she used to eat. She says because the food is “scary”

Idk how to break her of not being afraid to eat things she used to like and new things

She will refuse and drink her water.

Any advice ?
