Scientific studies have shown that children who don't take advantage of this period have much greater difficulty later on in accepting solids. Refusing solids later on can result in nutritional deficiencies and delayed growth. My guess is she will be more accepting of new solids since the concept of eating is not totally foreign to her. Now is the time for you to begin a weaning process. It will be more difficult than weaning a baby because you have a toddler on your hands.
Toddlers are notoriously poor eaters in terms of variety and quantity.
Toddlers hate new foods. All of these will provide challenges to you. I predict that it will be a slow and sporadic process, that will require patience, persistence, and understanding on your part. Begin by establishing a set meal and snack time with no more than three to four hours between feeding times. Next, you need to cut back on the Pediasure.
