Picky eater ?

So, there are things my daughter will never say no to like fruit, yogurt, apple sauce, anything like that.

But I find, especially with dinner, she eats a few great bites and then stops and doesn't want to eat anymore. I understand that appetite isn't a fixed amount each night but imngetting the vibe she just wants us to cave and give her some fruit on the side. We started becoming more strict but im so paranoid shes hungry. If she doesn't eat all her dinner. Anyone else feeling the the same or experiencing the same? Am I on the right track? Lmao
