Do not allow her to just have her favorites, put the new things out first, sit there and tell her that is what is for dinner, lunch or whatever. If she refuses then fine, take it away and proceed with your meal. If you allow her to be picky now it will esculate. I have had friends that waited until their child outgrew it and they just got worse. Now is the perfect time to talk to her about just trying things. I make my kids at least take a bite or two of new things. They can choose not to like it but are not allowed to say they don't unless they have tried it, it is "you don't know if you don't like it if you don't try it". Just giving your daughter her favorites is letting her control her nutrition, most kids would just love nuggets and mac and cheese. She will not starve, however don't let her dictate the meal plan or what is served. Be matter of fact, I never force my kids to eat, they can be done but when they come back hungry, dinner is in the fridge and they have to eat it before anything else. You can add ranch dip to veggies, my daughter loves ketchup on anything, even asparagus (I know yuck) but who cares if she is eating healthy. My son hates any type of seafood and fish, I allow him to not eat it as he has tried bites of it all, he eats other healthy stuff so I will allow him a few things he just doesn't like and that is fine. Don't make it a power struggle, however, keep her from snacking before meals, serve whatever you are making and she can either eat it or not, if not, she will not starve. Soon enough she will learn to try new things, eat what is for dinner. We ALL have gone through this at one point or the other so don't feel alone. Just be calm and cool about it, even ask her to help make the new thing you are trying so she gets excited about what she did. Good luck, kids do change their taste buds a million times just make sure she doesn't just eat her favorites all the time. The more spice and flavors she is exposed to the better eater she will be later. My friend has a three year old that is the same way and always has been, she always caves and gives her daughter cheerios as she is so worried about her being hungry, that will never solve the problem, promise she will not starve..hee hee...
