Such a sweet heart summer is … me personally I would let her watch something about plants or get a book about trees and fruit and read to her I would also let her plant/grow her own mini strawberries so she see the progress and it may help her understand about fruit and why we eat them
You don't terrify your child by referring to the fruit as he or her, it's not a being. That's why Summer got scared & cried when you described what would happen to the strawberry when frozen. Just teach them to call the fruit by what it is.
It is terrible for any one to tell a child that fruit is a human. Food and fruit are to be eaten, not described as a person. Awful teaching. Showing emotions for no reason.
