Agnes is
ADORABLE! 
Ralphie does look well adjusted to her presence, according to the photos. I'm sure he loves it. I had to laugh as you wrote she was able to put him in his place

mean in the true sense - as much as "down to business"...] ANYWHO-
"Congratulations" on your new addition!! Will look forward to picture updates!!
