Just a quick update.
The boys had their echos and they both do have innocent heart murmurs - absolutely nothing to be worried about.
They are both, however, growing like fertilized weeds. At their appointments, Zach weighed 15lbs 9oz and Max weighed 15lbs 5 oz. Both were 24" long - officially two footers.
They're doing great - laughing, smiling, interacting and everything. Never thought parenthood would be this cool.
Will blog more later.
