Early education follows the principles from simple to complex, from concrete to abstract, and step by step. Obviously, the second one is simpler and easier to use than the first one, and it will be easier for a one-year-old baby. I suggest you transition from the second to the first. And then gradually advance. Setting too difficult levels at the beginning is not conducive to the cultivation of children's self-confidence, and there are cases where children find it too difficult and lose interest.
