All this PPD talk got me thinking of one from my childhood, the groom was a cousin of my dad. 
B&G met and eloped in less than 2 weeks. Wedding announcement goes out. Gifts are sent.
Upon return 2 months later to G's home town they had a formal AHR. With registry 
After 6 months they had a huge Church wedding with the works. Showers, bach parties, big white dress, cake cutting, dances you name it and yes another registry.
I remember my moms head just about exploding upon receiving the church wedding invite. 
Divorced before 2nd anniversary.
