I have made the mistake of getting lazy and feeding my 15-month-old a lot of the same easy foods for a few months (avocado sandwiches, gerber meat links, frozen peas, carrots and corn and a broad array of fruit plus a variety of dairy). This has made her overly hesitant to try new foods, especially cooked foods from recipes. Any advice? If I put it on her tray and she pushes it away what do I do? TIA!
