Do Carson and Christian look alike?

If you've seen the boys, or pictures of the boys, you know they can look pretty similar sometimes and then others, not even close. But last night, Aunt LiLi, Christian and I went to a baseball game and Christian was telling LiLi that he looks like Chris and Carson looks like mommy. LiLi added "And you look like your brother". Christian thought about it and then agreed saying "Yes, sometimes I have red hair" :o)
