I dreamt that my aunt and uncle (who already have a 2 year old son) had another son. I adored their adorable baby and took a lot of care of him (for the 2-3 days the dream spanned) and protected him.
The dream may signify your desire for a new addition to your family or your desire to nurture something new in your life. The fact that you adored the baby and took care of him may suggest that you have a longing for more responsibility or a desire to care for something or someone. The dream may also indicate your protective nature towards those who are close to you. It could be a sign that you are feeling a growing sense of love and compassion towards others around you.
