Children like to eat in kindergarten, because the food in kindergarten is delicious and nutritious. Teachers also make recipes by understanding the preferences of kindergarten children, so the dishes they make are naturally liked by children. If a child is picky about food, the teacher will definitely educate him seriously and make this child a negative example for everyone, so that other children will not be picky about food. Kindergarten meals are also delicious, because teachers and children eat the same food. If you don't eat well, the child will definitely lose his appetite.
The atmosphere in kindergarten is good. In kindergarten, everyone eats together. When eating, we can discuss interesting things together, and there are many children here who are eating, so your children are naturally eating, sometimes unconsciously eating so much, because children are more playful and noisy, and may even talk while eating. At home, there is no one to chat with children, and children may eat less. Plus, I am happier in kindergarten, so my appetite will get better.
In kindergarten, everyone eats the same food, so sometimes there are competitions. For example, whoever eats first is a good boy, so children may eat quickly in order to get praise. But at home, there would be no such atmosphere. Parents are inferior to teachers. Maybe it's because your children prefer kindergarten teachers, so they do better in kindergarten. This is normal, don't worry too much.
