Dreams about babies often symbolize new beginnings, projects, or responsibilities in your life. In your case, the fact that your cousin had a baby for you might suggest feelings of reliance on others or the idea that someone else is taking on a role or responsibility that you feel is yours.

The baby being unusually heavy at 11 lbs and already resembling a toddler could indicate that you feel overwhelmed by a situation that seems to have matured too quickly or that you are facing responsibilities that feel too heavy for you to carry. It might also reflect your feelings about growth and development in your life—perhaps you're grappling with changes that feel sudden or burdensome.

Consider what areas of your life are currently demanding your attention or where you might feel a lack of control. This dream could be encouraging you to reflect on how you manage these responsibilities and whether you need to seek support from others.
