When you "track" the package, does yours say "Guaranteed by 3pm?" If so, I would call your post office. Mine said 3pm and I got the call at about 9am. I live about 25 min west of Danbury.
No babies yet? I sure hope they come today. The postal system seems to be slowing down. I ordered two sets of eggs recently, and the 2-3 day priority shipping eded up taking 5 for one and 6 for the other..
