Yeah, although it is frustrating; I have always heard and followed the same advice-that they will go through phases like that; and you just have to pretty much keep offering the foods; but if they have to survive for a week on hot dogs and cheerios; then that's what you do. Eventually she will get tired of it and eat what you offer her
I have been getting sneaky with my 2 though-doing stuff like pureeing a can of carrots and mixing it in with spaghetti or sloppy joes; that kind of thing.
