Children aged 0-3 can use it. Wow Box was launched by Eaton Shan Yu Group with more than 20 years of Montessori education experience. The professionalism and brand of the products are still relatively reassuring. I thought it was a little expensive before buying it for my child, but I think I have to buy him the one that suits him best. I've used it for almost 1 year now, and I think it's so valuable that I can benefit for life. This is the box from a month ago. There are 4-6 toys in each box, as well as picture books and parents' manuals. After buying it, you don't have to buy other toys for your children. There are Montessori early education classes in the supporting APP, so that our whole family can learn to raise children scientifically. Today's children are obviously more focused and responsive than other children of the same age in the community.
