We would never trade our mothers for any other person in the world. That’s because we love them to death, owe them big time for all the love and attention they gave us as children, and would not have become the people we are today without their care and dedication. That’s also because the laws of time, space and physics don’t allow such a thing to be done.
Of course, if such a thing could be done, we would have a hard time choosing a mother to replace the one we’ve got. The bar would have to be set pretty high just to weed out the potential candidates. These awesome celeb moms would certainly pass that bar, but not by much.
