Soon on September, 1st. In a fashion have appeared new rantsy with one belt through one brachium. How much or As far as I understand, such ranets with books and so forth will non-uniformly distribute or allocate a load on a skeleton of the child. Such "fashionable" things are how much harmful and whether they can lead to a scoliosis at the child with not strong joints. Can use is better habitual two-belt sumkami-rantsami?
