It won't help enough
With picky eaters, it's important to ensure a balanced diet
First, go thru fridge and cabinets & get rid of all junk food. If all that's given to her is healthy, she'll eventually eat some. Your child may need to try one particular food 18 times on 18 different days before accepting it, so don't give up! sometimes, giving the food in different forms, or mixed with other foods, helps.
