I bought a small plane for my daughter recently. Because my daughter watched the video and liked it very much, I placed an order for her daughter to buy it. As a result, people like blue ones. I bought someone a pink one in private. Although it doesn't affect the children's liking, the daughter wants a blue one more.
Although children like to eat cakes, it is not recommended to buy them. Children's health is the most important thing. Picture books can cultivate children's reading habits and lay a good foundation for the future, so I think classic fairy tale picture books are the best choice.
