(1) Try different types of food at earlier stage, even snacks (after meals), it is to explore different food profile;
(2) Try making food with toddlers so they understand the treasure of food making and want to eat what they make;
(3) Change the preparation of food / food style, e.g. if they do not eat vegetables, we can chop the vegetable and warp it inside meat dumpling, they will sure eat!
