Granted BBZ was bigger than LMA was at birth, but these two are like night and day. LMA was/has very fair complexion while, granted BBZ has been fighting jaundice for the past 2 weeks, he appears to have his father's spanish heritage with slightly darker complexion. LMA was smaller by 4 ounces, but BBZ pulls his legs up to his chest like a little frog and appears to be smaller. LMA was a big time crier, where as BBZ seems to be calmer and quieter.
I'm sure over the next couple weeks, months, and years more and more differences will pop up. But there's no doubt that I love my boys just the same (even if LMA is acting out now).
