I get this question at least 3 times a day (when we are out - if we walking the neighborhood, some one ends up asking, too). It makes me laugh because my mom got the same question with 2 of the 5 boys - Christopher and Brendan. Years ago, you really couldn't tell the difference until you were close up, but today there are a few similarities.
Here are my boys - what do you think?
Mommies of more than 1 child, do you get this question a lot too?
