Picky eater

My 3.5 year old daughter is such a picky eater. She basically only eats chicken fingers and toast and a few other things.

Tonight I made her mashed sweet potatoes and meatballs and veggies and she threw a complete fit and screamed and cried and said how yucky it was without taking a bite.

Daycare says she eats food there no problem.

I’m losing my mind. She never eats for me and I feel like I can’t feed my child.

Should I just give her chicken fingers every night so she at least eats? Any ideas?
