If she's refusing to eat food she used to eat, it's just a phase. It could be a dental issue, or she's trying your limits. My younger sister went through it and my older sister's kids are going through it. They'll grow out of it, or they'll become picky for life and people will hate them for it. Not much you can do about it except offer her a varied diet and insist that she eats something before going to bed.
Being Scandinavian, we always had rye bread and cold cuts in the house. If we didn't like a dish, we were told that we could go make ourselves a "
leverpostejsmad" (open liver pate sandwich). I don't recall ever doing that, though, because whatever was being served was better than a rye bread sandwich with liver pate. I like liver pate, but it's not very interesting when served on rye bread (traditional open sandwich here).
It's important that you don't bribe your kid with something she wants, like candy or junk food. That's the entire point of her charade, if it's not a dental issue. She wants the stuff she knows and loves, so she's refusing to eat anything else, hoping you give in and let her have the other stuff. If you tell her that she can have junk food tomorrow if she eats her carrots today, she'll realize that it's working and keep doing it.
Make her some
spaghetti bolognese. You can put all kinds of vegetables in the sauce (I suggest ground carrots, but be careful with the onions) and she'll get her dose of meat as well. She liked pasta products, right? Add some ketchup to sweeten the dish.
You can also make some
frikadeller (pan-fried dumplings). Seriously, kids love that stuff here.
Like I said earlier, it's important that you don't bribe her. Bribing is exactly what she wants. It would be like Paris and the vikings all over again. The vikings sailed down to Paris and held the city ransom. The Parisians, being French and all, surrendered and paid the vikings who then left, as promised. Next year, however, the vikings returned and demanded more...
Sorry, I'm in the middle of writing a lesson plan about viking travels and that comparison just popped up.
