20months toddler picky eater

Salam & Hi mommies.. nak mintak pendapat mcm mana nak naikkan selera makan my 20m old toddler. She refused to eat proper meal. Gigi dah banyak naik plus yg beberapa gigi yang on their way out. She only wants to eat cheese, yogurt, her baby rice/corn crackers and milk. Nasi putih pon kadang2 je dia nak. I’ve tried butter fried rice, porridge, eggs with cheese (last time this was her favorite), noodles, spaghetti, other pasta.. not working ?? I also tried giving her Appeton lysine..
