Even if parents don't mind, they can give their children a ball of dough to play with, which is much safer than buying plasticine for their friends. It's a bit verbose: Because the indigenous Maori culture in New Zealand thinks that food is sacred and can't be used as a toy, the use of food in kindergartens here is relatively restricted, but we also try to provide children with opportunities to explore without violating cultural taboos, such as dyeing rice/dough before playing with them. The culture of many families in China also emphasizes respecting and saving food, but think about it, children really don't need too much. In addition to the food that one-year-old friends can already eat, what other small things can be played or divided by themselves? The olfactory stimulation of playing with food is also a good sensory experience, and rich sensory stimulation can promote the development of children's cognitive nerves.
