Probably not enough detail provided for us to make even an educated guess as to what this might mean to your dreaming mind. The fact that they are all other women's babies and not your own, and that they are all boys may or may not be significant.
It could just be a statement of the obvious that many boys bear a distinct facial resemblance to their own mother, an expression of your own desire to become a parent at some later time when you getting pregnant would be regarded as being good news (do you have a preference for a son), or alternately it may have absolutely nothing to do with real babies.
Babies in dreams often symbolise new beginnings, or us starting a pet project. When people say possessively that
this is my baby and I am therefore making myself completely responsible for it being a success, they are using the same symbolic meaning of the word baby to which I am referring above.
