Regarding "Delivery #1":
As far as I know, the baby hasn't arrived yet. From what I've read, it sounds like it's probably been a long, hard past couple of days, but it shouldn't be much longer...
Regarding "Delivery #3":
Why doesn't USPS update their "Track & Confirm" information more often? The first, last, and only info I have from them is from May 3rd, which is kind of ridiculous when I expect the package to arrive either tomorrow or Saturday. (I think that at least once before, we received a package before they updated their info to indicate that it was anywhere in the area.) If they're not going to update more often than that, why bother having a track/confirm feature at all?
