Hi there,it's great that you want to involve your 3-year-old in the learning process. You're absolutely right; it's a good idea to let him participate as he wants to, in a fun and relaxed manner. For the 4-year-old, you can consider using educational software like Magic Desktop. It offers age-appropriate activities and games that can engage both children in a productive way. This way, they can enjoy the learning journey together, each at their own pace, and it can be a positive and enriching experience for both.
