Dreams involving babies often symbolize new beginnings, innocence, or potential. In your dream, the miniature baby could represent a part of yourself or an aspect of your life that feels vulnerable or in need of care.

The act of throwing the baby in the air and attempting to harm it may reflect feelings of frustration or a struggle with responsibilities. It could indicate that you are feeling overwhelmed by something in your life and are grappling with the consequences of your actions or decisions. The guilt and fear that emerged after you left the baby suggest that you may be worried about the impact of your choices on others or a fear of being judged for your actions.

Walking away from the baby might symbolize a desire to escape from a situation or responsibility that you feel ill-equipped to handle. The reasoning about someone else leaving their baby could reflect a wish to shift blame or avoid accountability for your feelings or actions.

Overall, this dream may be prompting you to reflect on aspects of your life that require your attention and care. It could be beneficial to explore feelings of guilt or responsibility in your waking life and consider how you can address any underlying issues that may be causing you distress.
