Boy do I know how frustrating having a Picky eater is! My #3 son who is 13 has always been a picky eater. He started off with problems when we started him on stage 2 baby food. He was born premature and they thought that maybe he had a sensory disorder because he was also picky about how things smelled and felt too. So his Early Intervention team started working with textures. They would dip the Gerber baby gum/ teeth brush in his baby food and roll it around so he got used to the feel of textures in his mouth, and it did nothing to help. As he got older we had to supplement him with Pediasure at our doctors orders. Lincoln does not eat Junk food either. He likes Raman Noodle soup, Chicken brest, Pasta in a non chunky sauce, corn, carrots and broccoli and Yogurt. We also cant buy milk at Meijers food store cause he says it taste funny, but milk from Krogers and Wall mart are fine
He is very small for his age too, he is in a size 10 and will be 14 in April! We worry about his eating habits because it just seems like he don't eat! His Pediatrician advised us not to make an issue about his Picky food habit, cause it actually could make it worse! They talked about nutrition and how important a Balance diet is with him. They suggested that we should always offer him what the rest of the family is eating. If he choses not to have it then we always have the cooked chicken, soup or pasta for him and he reheats it up himself in the microwave. His Doctor said as long as he is eating something, he aint going to starve
So that is what I do.
You might want to bring it up with her doctor and maybe they can give suggestions for you and her that will help you out. Good Luck!!
