Dreams about giving gifts, especially to loved ones, can often reflect your feelings of care, support, and desire to nurture those relationships. In your dream, buying a trike that turned out to be a little tricycle may symbolize your intentions versus the reality of the situation.

The tricycle could represent a feeling that the gift you intended to provide—perhaps something that signifies maturity or independence—turned out to be something more childlike or simplistic. This might suggest concerns about your son’s current state of development or independence, or it could reflect feelings of wanting to help him, but feeling limited in your ability to do so.

Consider whether there are areas in your son's life where you feel he is still dependent or where you wish he would take on more responsibility. This dream may be inviting you to reflect on how you can support him in his growth while also allowing him the space to mature at his own pace. It may also suggest a need to adjust your expectations or approach in your relationship with him.
